6 Cycle Comparison: Marquette Versus Billings Versus DOT Fertile Windows

Have you ever been curious what your fertile window would look like in multiple methods?

In this blog, I show 6 cycles with various fertility signs and method interpretation including: the sympto-thermal method (Sensiplan rules), Marquette method, the Billings Ovulation Method, and DOT (a calendar method that was recently purchased by Clue app and is a new FDA approved birth control). I chose to include representation for only studied methods of fertility awareness: sympto-thermal, sympto-hormonal, mucus-only, and calendar method.

All charts are from the Read Your Body app, a flexible app for all methods that I highly recommend!

Some things to know before reading:

  • Marquette allows sex any time of day within their rules. My calculation rule lasts until the end of day 7.
  • Sympto-thermal method allows sex any time of day during first 5 days of menstruation, but the first safe day in the luteal phase must be used in the evening. My calculation rule is day 5.
  • Billings Ovulation Method allows sex in the evenings only and on rotated days in the pre-ovulatory time of the cycle. Days of bleeding where mucus cannot be observed are not allowed. However, since you can have sex any time of day post-ovulation with Billings, sometimes cycle day 1 is available if you have sex before bleeding occurs.
  • DOT allows sex any time of day within their rules. It automatically opens my window on day 7.

Cycle 53

Consecutive Fertile Window for Expected Abstinence:

Billings: 8 days

Sympto-thermal: 12 days

Marquette: 12 days

DOT: 12 days

General remarks: This is an extremely standard cycle in length and mucus patch (the average person will have a 5 to 6 day mucus patch when charting). I believe this is a great example of what methods would look like for someone of the average cycle length.

Cycle 54

Consecutive Fertile Window for Expected Abstinence:

Billings: 9 days

Sympto-thermal: 21 days

Marquette: 15 days

DOT: 12 days

General comments: My average coverline is 96.8 to 97.0, so regardless of earlier high temperatures and some illness I felt confident marking this coverline and temperature shift. Due to continous long, clear-ish mucus, my sympto-thermal peak was extremely delayed. Billings is a sensation focused method so I was able to mark my peak at an earlier time and have less expected abstinence.

DOT gave me a very risky day on this one. It is possible I could have been ovulating near the safe day. However, that would have only left 9 to 10 days for implantation and I had spotting, so whether this truly could have ended in pregnancy is up in the air. Even with well-timed sex, pregnancy will not always occur.

Cycle 55

Consecutive Fertile Window for Expected Abstinence:

Billings: 6 days

Sympto-thermal: 12 days

Marquette: 12 days

DOT: 12 days

General comments: This small fertile window in Billings might look scary to some, but it is not possible to get pregnant when the cervical mucus plug is truly closed. I have about one cycle like this every 13 cycles. I was also using the Kegg device during this cycle which is placed internally and reads electrolyte levels to determine the fertile window. It gave me the same 3 day dip for a fertile window, so I feel even more confident that those days were truly dry. I am missing temperatures on this one because my thermometer glitched and would not give me readings on these days. Sex day 1 was allowed because menstruation didn’t start until 5pm.

Cycle 56

Consecutive Fertile Window for Expected Abstinence:

Billings: 8 days

Marquette: 11 days

DOT: 12 days

General Comment: This was an extremely heavy period so I had no period days available in Billings. Even though the other methods gave me available days, I couldn’t have used them due to the pain, so ultimately the other methods didn’t really help out on more safe days.

Cycle 57

Consecutive Fertile Window for Expected Abstinence:

Billings: 10 days

Marquette: 14 days

DOT: 12 days

Cycle 58

Consecutive Fertile Window for Expected Abstinence:

Billings: 9 days

Marquette: 11 days

DOT: 12 days

General Comments: Marquette monitor missed my peak on this cycle. It misses peak on up to 10% of cycles. I relied on meeting LH rules instead of the monitor. Sex day 1 was allowed because menstruation didnt start until 1pm.

Reflecting on What’s Best for Me

I’m currently on cycle 59 charting, and I have tried a ton of methods. Right now, my ideal method is Billings and LH tests as a bonus marker.

While it may appear that Billings gives less safe days in some instances, what is most important to me is having the smallest consecutive fertile window. Having less expected abstinence actually makes me more likely to follow the rules. I was completely unsatisfied with only being allowed period sex in the sympto-thermal method because I have period pain issues. That means that I basically had no safe days at all in reality before ovulation with sympto-thermal.

I originally felt very enthusiastic about Marquette method. However, after 6 cycles of using the Clearblue Fertility Monitor, I realized that it always caught my LH surge after the cheap LH tests. In addition, it missing my peak even once is frustrating for the cost of the product. For that reason, I have decided to stop using the monitor when I run out of tests. I can use a 15 cent LH test and get the period prediction aspect (LH is my most steady indicator).

The DOT app tends to give me a risky cycle whenever I ovulate late and have a shorter luteal phase. I do not rely on this for pregnancy prevention. Overall though, DOT has not given me many risky ways. I use it for long-term period prediction, and it is the most accurate period predictor I’ve ever used for planning months in advance.

What to Consider Before Switching Methods

1. Why are you unsatisfied with your current method? Is it the amount of safe days, or is it the routine that you don’t like?

2. Do you have medical needs that could be addressed by another method?

Sometimes the grass isn’t greener on the other side, but if you are like me and can’t have period sex or don’t want to have period sex, methods like Billings without calculation rules will almost always include more safe days if you are dedicated enough to learn the method and chart it accurately.

Folks in irregular cycles like in postpartum time or with PCOS may benefit from more flexible methods without calculation rules

A Day in the Life of a Billings Ovulation Method User

Have you ever wanted to know what it is like to chart with the Billings Ovulation Method? This blog attempts to give an overview of what it is like for one individual to chart with the Billings Ovulation Method (BOM) over a single cycle. I go through each day of the cycle and explain my overall charting habits. All times are just approximate. I get personal and discuss some challenges I experience with natural family planning. BOM involves tracking sensation felt at the vulva along with the visible appearance of cervical mucus as a person goes about their day to day activities.

Day 1: Record heavy bleeding. Heavy bleeding feels wet. Done! Users are not allowed to use heavier days in the Billings method when avoiding pregnancy. This is a true day one of a cycle because it was preceded by a Billings peak day.

Day 2: Record heavy bleeding. Heavy bleeding feels wet. Done!

Day 3. Record medium bleeding. Medium bleeding feels wet. Done!

Day 4: Very light bleeding. It is now possible to observe my basic infertile pattern of dry.

8am: I feel dry and see a small amount of blood.

10am: I still feel dry.

8pm: I still feel dry. I see no mucus. Sex is allowed in the evening of this day. We use this day.

Day 5: Extremely light bleeding. Technically this day is not allowed for intercourse since I used the day before and Billings method rotates alternative evenings. We use this day anyway #rulebreaker

Day 6: I feel dry. I do not see anything. I record this day as “possibly fertile” since I broke a rule and used the day before. Every day after intercourse gets this white stamp in the pre-ovulatory time of the cycle.

Day 7: My basic infertile pattern of dry is still there! I notice nothing the entire day in the bathroom and my vulva sensation is dry. Sex is allowed in the evening. I consider my evening 8pm because I go to bed around 9pm on average. We use this day.

Day 8: I feel dry all day and see nothing. However, this day is not allowed since Billings alternates days. We skip this day.

Day 9: I feel dry all day and see nothing. However, we do not use this available day because we are both tired. It happens!

Day 10:

9am: I feel a bit moist. I don’t see anything when wiping in the bathroom.

11am: Still feel moist. I do not see anything in the bathroom.

2pm: Still feel moist. I do not see anything.

4pm: Still moist. Nothing seen.

4:45pm: Walking to my car from work. Still moist!

8pm: Overall observation for the day is moist. I record it. The fertile window has opened. This is known as the point of change.

Day 11:

7am: I feel moist as soon as I walk to the bathroom. I see very scant clear mucus on the tissue.

I do not see or feel anything for the rest of the day.

8pm: Overall observation for the day is “moist, clear”

Day 12:

7am: I feel moist, but see nothing.

10am: I feel moist, but see something white.

8pm: The feeling remains the rest of the day. I record “moist, white” for the day.

Day 13:

7am: I feel dry.

11am: I still feel dry.

1pm: I feel wet sensation when walking to my office. This is a change, so I keep that in mind.

I feel damp the rest of the day. I never see anything in the bathroom. I record “wet” as the most fertile sensation that day.

Day 14:

6:30am: I immediately feel moist.

9am: I see long clear strings when wiping in the bathroom.

11am: I have a wet sensation when walking around.

3pm: I walk around my work place. I still feel moist.

5pm: I see clear strings again.

8pm: I record “wet, clear strings” on my chart.

Day 15:

7am: I feel a gush as soon as I wake up. I do not see anything in the bathroom.

9am: I see scant, clear mucus on the tissue when wiping.

11am: I feel very wet walking around my work place.

1pm: I do not see anything on the tissue.

3pm: I do not see anything on the tissue.

5pm: I feel wet sensation while making dinner.

8pm: I record “wet, clear” as my observation for the day.

Day 16:

7am: I do not feel or see anything when waking up.

9am: I still do not feel or see anything.

12pm: I go for a 20 minute walk. When I get back, I feel slippery sensation. I go to the bathroom and see copious amounts of long, clear mucus.

8pm: I felt slippery the rest of the day. I record “slippery, long clear” on the chart.

Day 17:

6am: I feel dry when waking up.

8am: I don’t see anything or feel anything.

11am: I don’t see anything or feel anything.

8pm: The day was nothing felt, nothing seen all day. I record dry. This means yesterday was my peak day because it was a changing and developing pattern ending in slippery followed by an abrupt dry up to no longer wet or slippery.

Day 18 and Day 19:

I have the same experience as day 17. I pay attention all day and observe no mucus or sensation.

Day 20:

Ovulation is expected to be over and the cervical mucus plug has re-closed for the cycle. Sex is available any time for the rest of the cycle until day one of menstruation occurs. I can chart, but it is not necessary to wait until the evening and observations are less important as sex may interfere at any time.

Day 28: I record heavy bleeding and the rules restart.

Real Talk: Diffulties / Obstacles With Billings Not Seen on the Chart

These are things that I find can be difficul in my own personal experience. I know that people in really long cycles or with other irregularities may have different issues than me.

Challenge One: Alternative evenings only can be a struggle, and it seems even harder for me right before the fertile window opens due to my mood at this time of the cycle. This follicular phase is much longer for me than my luteal phase on average, and this means alternative evenings is the rule for most of my cycle. If someone has a partner with a conflicting schedule, this can especially be offputting. I think anyone who is going to practice this method should consider whether this is practical for their lifestyle.

Challenge Two: Expected abstinence in Billings can be hard, and I have fairly short fertile windows on average. I originally practiced sympto-thermal, and I switched to Billings when I realized that overall consecutive abstinence was much less overall (for my own cycle, Billings: 9 days, Sympto-Thermal: 14+ days). I tend to break some rules still, but this is much more suitable for my fertility intentions level than sympto-thermal.

Look out for my next blog on “A Day in the Life of a Marquette User.”

Disclaimer: Do not try to learn how to chart from this post. Everyone has their own unique cycle and this is just an example of charting with Billings in a regular cycle. Please reach out to me if you would like to learn this method with me as your guide. Alternatively, you can find a teacher here.

An Honest Review of Kegg

For the last 5 cycles, I have been using the Kegg device that reads the electrolyte levels present in the cervical mucus in the vagina. To use this device, someone would insert Kegg in the same two hour period of time during the day. Kegg takes approximately two minutes to give the user a reading on the graph. Click here to read an article on the science behind Kegg.

This product is an exciting development in the femtech field because it actually does read a real-time fertility sign. Cervical mucus is completely necessary for natural conception to occur. Without the presence of cervical mucus in the cervical crypts, sperm cannot to get to their destination to reach the egg. For this reason, anyone trying to conceive needs to track cervical mucus or use an alternative device such as Kegg (or a device that reads estrogen levels) in order to time intercourse for when they are most likely to conceive.

Here is what a Kegg chart looks like while lined up with my real-time Billings Ovulation Method cervical mucus observations.

In this image, the three most fertile days with Kegg are represented by the three green bars. This lines up very well with my Billings Method observations. When reading a Kegg chart, you are looking for a set of high values – followed by a dip in the chart – followed by a rise.

Who is Kegg right for?

I know that the question on everyone’s mind is whether Kegg can be used to re-place cervical mucus observations for avoiding pregnancy. Unfortunately, the answer is that Kegg is not suitable for avoiding pregnancy. It is designed to find the most suitable days for conception. For those avoiding pregnancy, the fertile window has to be much longer than the window that Kegg gives. Until Kegg has been studied for pregnancy avoidance, I cannot recommend it as an alternative to cervical mucus checks which must be made multiple times of day until the evening when someone is strictly avoiding pregnancy.

Kegg may be right for someone who wants to conceive without needing to take a class or read a book on cervical mucus. In my experience, for the most part, it detected my most fertile days in a way that would likely lead to conception if used.

Kegg may not be right for you if you have a very erratic schedule. Since it has to be used in the same two hours and cannot be used up to 8 hours after sex, this may make Kegg harder to use. I personally experienced some issues timing Kegg correctly because of the nature of practicing a fertility awareness method meaning that I have sex at different times of the day based on what part of the cycle I am in.

My 5 Cycles with Kegg

The following images are my five cycles with the Kegg device compared to urinary hormones and cervical mucus observations. The three chicks in the egg represent the three most fertile days with Kegg. All of the charts are from Read Your Body by the Body Literacy Collective.

My Overall Impression of Kegg

I am often very critical of femtech that gives predictions, and Kegg does give calendar predictions at the beginning of the cycle. However, overall, I believe that the readings I got with Kegg did line up with my real-time signs for the most part. Since this device is for conception purposes, it does seem to highlight the most fertile days. I did have to switch from mornings to evenings on my Kegg readings to get clearer charts. I also find Kegg extremely hard to use in my luteal phase when sex may occur at any time of day, but this isn’t a huge problem since you can stop using Kegg once it has detected your rise. For those who want to add an extra layer to your chart or chart to conceive only, I can recommend the Kegg device.

Customer service with Kegg has been excellent. The team is very reachable. If you would like to see more Kegg charts and learn from fellow Keggsters, you may join the Kegg facebook group for conception or for those using it along with signs to avoid.

What is Walking Sensation?: How to Check for Vulva Sensation While Going About Your Day

This article was originally published on fertilityawarenessmethodofbirthcontrol.com


While some fertility awareness based methods use wiping sensation, a large majority of sympto-thermal methods (as well as mucus-only methods such as the Billings Ovulation Method) use some variation of walking sensation.  Walking sensation is the feeling someone experiences at the vulva while going about their day to day activities. A good way to think about it is what it feels like to feel menstruation begin. Most people understand that this causes a wet feeling at the vulva without even needing to look to see the blood. Likewise, walking sensation can be felt at the vulva without needing to look for visible mucus. 

This feeling might feel like something is falling out of your vagina. It could feel moist, wet, sticky, lubricative, slippery, or similar terms. This sensation opens the fertile window even if no visible mucus is seen. In fact, it is common to have walking sensation open the fertile window before any mucus is seen. It is also common for slippery / lubricative / wet sensation to be set as peak day (depending on your method rules!). Again, this would count as a fertile day even without visible mucus being seen.

Walking sensation is a practice in mindfulness. It involves tuning into the nerves at the vulva as you go about your day. Notice how it feels when you walk around, exercise, or otherwise move throughout the day. Wearing tight pants or synthetic fabric underwears can make it harder to feel. If you are having trouble tracking walking sensation, consider wearing a skirt or dress for a full cycle. This can be helpful if you are having trouble tracking it. Another common suggestion to help learn it is to “chart blind” for one full cycle (obviously you will need to refrain from unprotected sex if changing up your method!). Charting blind means charting your sensation without looking at your visible mucus. This forces you to rely on the feeling at the vulva. Note that the Billings Ovulation Method which relies on walking sensation as the primary sign has done small studies with blind women who were able to chart their patterns with it while never being able to see visible mucus. 

If you are interested in learning more, reach out to an instructor. If you want to use it as a part of a mucus-only method, the Billings Ovulation Method focuses more on it than any other existing method. I personally teach this sensation in my Billings Ovulation Method class.

In Defense of Mucus-Only Methods (Specifically Billings Ovulation Method)

In the fertility awareness world, there are many misconceptions about mucus-only methods. While I cannot speak to mucus-only methods that I have not trained in, I can speak for what I have learned in training in the Billings Ovulation Method. There is so much history of the development of the method that I cannot touch on everything here. For those wanting to learn more, this document goes over some of the history of the method. Outside of that, WOOMB has many useful links.

First and foremost, the usual criticism leveled at mucus-only methods is that they have a low efficacy rating when compared to the sympto-thermal method. However, this is much more nuanced than it may appear at first glance. Let’s look at the most often quoted study for Billings.

This section of statistics is copied directly from a WOOMB International breakdown found here:

1976-78 an independent trial was conducted by the WHO, in five countries (India, the Philippines, New Zealand, Ireland and El Salvador).

This study had two phases:  
869 couples entered the three-month ‘teaching phase’,
725 couples continued in the 13-cycle ‘effectiveness phase’,
with a total of 10,215 cycles in the entire study.

The teaching phase showed that in the first cycle of charting, 93.1% of women were able to record an identifiable ovulatory mucus pattern denoting fertility, and that by the third cycle of charting, 97.1% of women had an excellent or good interpretation of the method.

The results for the entire study were:
2.2 pregnancies/ hwy    (per 100 woman years)  –  method-related pregnancy rate
22.3 pregnancies/hwy  (per 100 woman years)   –  total pregnancy rate

The total Pearl Index  – 22.3/hwy  comprised:
• Conscious departure from the rules of the method: 15.4/hwy.
• Inaccurate application of instructions: 3.9/hwy.
• Method failure: 2.2/hwy.
• Inadequate teaching: 0.3/hwy.
• Uncertain: 0.5/hwy.”

The first thing you should notice is that perfect use was 97.8%. This is pretty high. The second thing you should notice is that typical use includes people who knowingly broke the rules! All typical use always includes this. This statistic of 22.3% typical use failure is used to scare folks away from mucus only, especially when compared to one specific sympto-thermal trial by Sensiplan. However, the Thyma double check sympto-thermal had a 35% typical use rate in one trial. No method is impervious to bad typical use rates because this is dependent on how open someone is to pregnancy, as well as cultural factors. This is a flaw (depending on your perspective) of all FABM methods; someone can choose to achieve pregnancy because fertility is not suppressed.

The next thing to consider is that the older statistics of the Billings Method were based on a different peak rule, a very similar peak rule to which all sympto-thermal methods have adapted. As Billings continued to develop, the method was strengthened by over 850,000 hormonal assays completed by Dr. Brown which tested estrogen, follicule-stimulating hormone, progesterone, and luteinizing hormone. These tests were matched to Billings Ovulation Method charts. The method has been scientifically validated in over 10 total trials.

As the method was studied, the peak rule was changed to help women recognize patterns of fertility and infertility. They discovered when the specific peak rules were met, a changing and developing pattern of discharge and sensation <more specific rules apply to this>, ending at a slippery sensation felt at the vulva 《with walking sensation》and followed by an abrupt change to no longer slippery or wet, that a woman could detect a false mucus patch build up without the need for temperatures. Because of the science that Dr. Brown, Dr Evelyn and John Billings, and Dr. Odeblad verified through numerous studies, they were able to strengthen the mucus only method enough to no longer rely on temperatures without fear of double peaks. The most recent Billings study in China found a 100% perfect use rate and a 99.5% typical use rate when users were very strictly avoiding and highly motivated with the rules.

In short, the Billings Ovulation Method is very effective and for careful charters does not suffer the problem of false peaks. Again, I have barely scratched the surface of all the trials and science involved. I recommend researching Erik Odeblad and the pockets of shaw for more information.

So why do mucus-only methods get such a bad wrap? In the secular communities, I think there are a few main reasons.

1. The methods must be learned through a teacher. Learning these methods takes dedication and regular live (or online) meetings with a real person. Most folks don’t feel like making this effort or think they can’t afford it. Billings has a policy to never turn anyone away in need. Many do free services or payment plans when asked. There is also a charity associated with Billings that can sponsor Catholic couples to help them afford classes.

2. The next reason is that many sympto-thermal users have fundamental misunderstandings of what Billings is. As a certified sympto-thermal teacher and someone who has read about fifteen books on sympto-thermal, it is dissapointing how much of the original science of fertility and the cervix is left out of our materials. My mind was blown when I discovered how things really work when learning a mucus only. From the pockets of shaw to the functions of the cervical crypts, there is so much to learn that is not included in Taking Charge of Your Fertility. This does a great disservice to sympto-thermal charters.

3. Due to these misunderstandings, they think the method cannot be used by those with irregular cycles. They also may think that a non dry basic infertile pattern is not possible due to a misunderstanding of the science of the cervical plug and the effect of estrogen in the vagina.

Potential Cons of Mucus Only:

I do not say any of this to say that the Billings Method is right for everyone. It takes dedication and a willingness to follow the rules if strictly avoiding pregnancy. In addition, there are a few cons to mucus only.

1. A yeast infection or bacterial vaginosis would obscure observations and cause abstinence. However, arguably even a sympto-thermal user would need to abstain when they have an infection.

2. Women who are careless with mucus observations may end up with an unintended pregnancy. If you don’t want to track mucus carefully, this is not the right method for you. If you can’t follow the rules to safely have intercourse, such as evenings only during basic infertile pattern on alternate evenings in the pre-ovulatory time of the cycle, this method may be too restrictive for you.

3. A weak mucus patch that does not fulfill the stringent peak rules may cause more abstinence without a temperature shift to confirm. However, this often signals a potential health issue and should be investigated.

4. Mucus only methods do encourage abstinence when avoiding pregnancy. However, most sympto-thermals do the same. Anyone who is okay with an elevated risk due to barriers or alternative protected sex can always do what they want to do but should be prepared to face the consequences if a barrier method fails.

Conclusion:

Mucus only methods can be highly effective choices for avoiding pregnancy. Recent trials of Billings consistently show 99% or better with perfect use. In some cases, they may reduce abstinence because they allow women to identify false mucus build ups that do not lead to ovulation and non-dry basic infertile patterns. For women who want to eliminate barrier method usage, they offer a way to identify fertility in real time when in irregular cycles due to PCOS, postpartum, or perimenopause. This eliminates much of the extended abstinence or barrier method usage that sympto-thermal users may experience.

Why did I choose to become a fertility awareness instructor?

Why did I choose to become a fertility awareness educator?

Fertility awareness is the sex education I wish I learned in middle school.

When women actually learn how their fertility works, they learn that getting pregnant is not as easy as the drop of a hat. We learn to appreciate and live with rather than work against our fertility.

Almost every person who I’ve seen read #takingchargeofyourfertility or take a FAM class comes out of the experience saying, “Why have I not always known this information? I wish I could have known this when I was younger!” Learning fertility awareness changed my life, and I know it can change yours too.

Do I believe FAM is the right method of birth control for every woman?

No, it is probably not.

But I do believe that every woman should be taught how to understand her own body. What she does with that information is up to her.

Fertility awareness gave me the ability to avoid pregnancy on my own terms. It gave my spouse more knowledge about my body and the changes I experience during my cycle. It has strengthened my relationship in more ways than I can name.

If you want to learn FAM, I suggest getting an instructor. Check out this website for a list of instructors.

An Honest Review of Pearl Fertility Kit

I tried the Pearl Fertility Kit. During my first kit, I got a little confused when the kit did not seem to line up with my fertility signs. However, I contacted Pearl Fertility and they were super helpful. They sent me another kit for free, and it worked perfectly when I tried it this last cycle.

Pearl is a product marketing to women who are trying to conceive (TTC). The product explicitly states that it should not be used to avoid pregnancy. The kit contained 15 follicle stimulating hormone (FSH) strips, 15 luteinizing hormone (LH) strips, and 4 progesterone (PdG) strips. It also included a few pink dye pregnancy tests. As I am not currently trying to conceive, I did not use these.

The app claims to open a woman’s fertile window by scanning the FSH and LH strips and giving you a fertility window from these results.

If anyone wants to try this product, I highly suggest tracking your cervical mucus, as good quality cervical mucus (eggwhite, clear, stretchy, wet) is what allows sperm to survive to meet an egg. Progesterone tests need not be used until at least 4 days past your peak day (the last day of good quality cervical mucus). Even then, some women do not see positive progesterone tests until as late as 7-10 days past ovulation. For more information, visit Proov’s website linked at the end of this article. By charting your real fertility signs, you could use these tests more wisely.

Overall, I thought the Pearl Fertility Kit was super cool. FSH strips are a brand new thing, and I have high hopes for them being integrated into a real fertility awareness based method in the future. If you have the money to invest in Pearl, this can be a fun kit to experiment with. Basically you get to see three main hormones of the menstrual cycle play out. Pearl graphs them for you.

If you cannot afford Pearl, do remember that it is free to chart cervical mucus and that this is always the best indicator for when to have sex when trying to achieve pregnancy. Without cervical mucus, sperm will never make it to the egg on its own.

Here is what my Pearl chart for this month looks like:

The highest pink dot is my positive LH strip.

Here is my Pearl information compared to my symptothermal method chart. In this chart, FSH equals Ferning since Kindara does not have an FSH category.

The Pearl fertile window is indicated by the green lights. It did start my fertile window on a day pregnancy was unlikely since there was no mucus. The blue hearts represent the fertile mucus where sperm can survive. These two fertile windows lined up pretty well.

Overall, I would rate myself satisfied with this kit.

One tip:

From the calendar screen, you can override what tests Pearl is asking for. I only suggest doing this if you are charting your other fertility signs (cervical mucus and basal body temperature) and know that something is not lining up right.

In addition to the strips, Pearl has spaces to track intercourse, your period, and pregnancy status.

Now Opening Enrollment For December 2019 Fertility Awareness Course

I am so excited to be offering this new course for those interested in learning the symptothermal method of fertility awareness. The method I teach is based on the rules studies by Sensiplan. You can read about this study here.

I found fertility awareness after 7 years on the pill, and it really rocked my world. When I started practicing it myself, I realized that it was a grave injustice that women are not taught about FAM. Practicing FAM has put me in touch with my body more than ever before. It healed some of the mind/body split that I had developed through years of resenting my period.

Moderating in Fertility Awareness Method of Birth Control, the largest English speaking, secular fertility awareness group on Facebook at 25,000+ members, lead me to becoming a certified instructor through the Natural Family Planning Teachers Association (NFPTA). Starting in February 2020, I am pursuing a certification through Bebo Mia as a fertility doula to support women who are TTC. Outside of the fertility world, I am training to be a librarian. I have taught at the college level since 2016.

I teach a secular form of fertility awareness including information on barrier methods (condoms, diaphragms, etc). The NFPTA method has the same temperature rules as Sensiplan. I teach cervical mucus, cervical position, basal body temperature, and calculation rules (the doering rule and minus 20 and 21 rules). My distance course is offered on Moodle. It is a 4-week self-paced course that includes video charting examples and information on charting during all life circumstances (perimenopause, postpartum, postpill, and TTC). This class opens in December. Your partner is welcome to ask me questions and take the course along with you.

If you already have charting experience from reading TCOYF or the Sensiplan file (3 or more complete cycles), I will extend a discount to you if you decide to work with me. Reach out to me to find out more. I will also likely be holding a live introduction to FAM session in early December.

The best way to get in touch with me is through DM on my Instagram @chartyourfertility or through e-mail by completing a form on chartyourfertility.com. You can also follow me @chartyourfertility on Facebook

I will work closely with you so that you understand the rules, but it is ultimately on the user to follow them.

Shortcut charting, or “Wait… I don’t have to take my temperature every day?”

Many people come into FAM overwhelmed by all the data that they have to collect daily. It can be a bit of a turn off for those new to the method. They may wonder why they have to check their cervical mucus ALL day and then set an alarm on top of that.

When you first begin charting, it is vitally important to try to get the information down every day so that you can get into a habit and make sure that you are following the rules. Missing information will leave you with less complete charts that could leave you confused as to whether ovulation is confirmed or not.

However, once you have been charting for a significant amount of time and become confident, you can stop recording fertility signs once you have confirmed ovulation.

I am headed into chart number twenty-two successfully avoiding pregnancy with FAM, and I have been shortcut charting most of the time for about seven cycles now. I personally recommend confirming ovulation in 12 cycles before shortcut charting. This is so that you know how early you ovulate, your normal temperature levels, and how to tell whether something abnormal is going on in your cycle (ie sickness causing temperatures to be higher than normal or an abnormal cervical fluid dry up due to cold meds or some other medication).

Toni Weschler, author of Taking Charge of Your Fertility, recommends that women have several months of experience in the standard rules before taking any shortcuts. She offers some modified guidelines to follow and emphasizes that “contraceptive efficacy won’t be compromised as long as both your fertility signs have confirmed that ovulation has already been confirmed for that particular cycle.”

The Modified Rules

Temperature Taking

  1. You don’t have to take your temperature during your period. Toni explains that these temps may be unreliable anyways. However, if you have short cycles with early ovulation, you may need those temps in order to confirm ovulation. If you have a temperature shift CD12 or sooner, you will need some period temps in order to have enough temperatures to draw a coverline.
  2. You don’t have to take your temperature after you confirm ovulation with temperature rules. This means at least 3 high temperatures with a standard shift. If you have weak shift or a fall back rise, you must have the extra temperatures needed to fulfill those rules before you stop taking your temperature. Some people take their temperature again a day or two before they expect their period since it can (but not always) give an indication that menstruation is approaching.

Cervical Mucus

  1. You don’t have to check cervical mucus after you confirm ovulation. You will need to check until you meet peak rules (P + 3) and crosscheck this with 3 high temperatures before you can stop checking for cervical mucus. Again, if you have a weak shift or fallback, you will need to check until you meet the rules.
  2. From the day after your period until the day you observe peak type fluid, you should check cervical mucus continuously throughout the day and follow all rules for mucus checks. However, you don’t have to check cervical mucus multiple times a day once you observe peak fluid. If you observe peak fluid first thing in the morning, there is no need to keep checking. You have already recorded your most fertile observation for the day.

Those are the basic changes when short cut charting.

Here is an example chart.

This woman does not take her temperatures during her period. She begins taking her temperature on CD6 when menstruation ends. She checks her cervical mucus multiple times a day and follows the rules for checking until CD11. On CD11, CD12, and CD13, she observes eggwhite mucus first thing in the morning and doesn’t check again. On CD14-CD17, she checks mucus multiple times a day because she knows she needs at least a 3 day dry up (P + 3) to confirm ovulation. On CD 15, she has her temperature shift. CD16 is above the coverline. CD17 confirms ovulation because it is at least .4 F above the coverline. Ovulation is officially confirmed with both peak and temperature rules met. She takes her temperature again on CD26 to see if she gets a temperature drop indicating that her menstruation may begin soon.

People Who May Want to Think Twice about Short Cut Charting

Not everyone is suited to short cut charting.

  • Charting for Health: If you are charting for health, you may want to record your signs every day. Odd cervical mucus patterns and temperatures can indicate health issues. If this is your goal for charting, short cut charting may not be right for you.
  • Using Tempdrop: Tempdrop says to wear the device every day. If you don’t, it could disrupt the algorithm. As far as I know, they do not recommend short cut charting at this time. If you use this device, you may not want to short cut chart if you are worried about being at risk of pregnancy.
  • You aren’t confident in charting: If you are not confident in your ability to chart, you should NOT short cut chart. You should be 100% confident in your abilities before attempting this.
  • You are sick: If you are sick, you may want to chart more diligently and stay protected if you are uncertain about your chart interpretation.
  • You are only charting one sign: You NEED two signs in order to short cut chart. If you pick just one, you may be putting yourself at risk of unintended pregnancy. Ovulation must be confirmed with two signs.
