You may know that the Fitbit app has some built in menstrual cycle tracking features, but many people do not know that it has other features that may be useful for menstrual cycle tracking. In this article, I will review the pros and cons of the Fitbit app as it relates to cycle tracking for people who ovulate. For context, I use a Fitbit Charge III.
The most basic feature that Fitbit offers for cycle tracking is recording bleeding dates of menstruation and then displaying a predicted fertile window based on average cycle length.
The user needs to remember to input menstuation each cycle. Once it is inputted, Fitbit will generate the blue fertile window. This fertile window should NOT be used for avoiding pregnancy, as it is only based on cycle length and not real-time fertility signs like cervical mucus or basal body temperature.
Once menstruation is entered, it will also begin a countdown until your next predicted menstrual cycle.
Unfortunately, I do not find this basic feature very useful for anyone who has any cycle variation. Even though my cycle length has increased over the last year, Fitbit has not automatically updated my cycle lengths. The app does not appear to be very adaptive without user input.
In addition to tracking bleeding the app offers options for:
Plan B (morning after)
Ovulation tests (better called luteinizing hormone tests)
Cervical mucus (Taking Charge of Your Fertility categories)
Cyclical symptoms like acne
It is rather disappointing that the app does not include options to mark pregnancy when it occurs, especially since we know that this changes daily calories burned and heart rate, to name just two effected areas of the app.
A really cool feature that I do like is the ability to show cycle trends like flow intensity and cramps. The same screen that displays this will also let you scroll through all past cycle lengths.
In the settings of this screen, you can also decide to toggle off predictions. For people avoiding pregnancy, I do recommend either ignoring or toggling off predictions in the Fitbit app. The app allows you to choose your current birth control method as well.
Outside of the designed menstrual cycle tracking features, I want to highlight resting heart rate as a potential exciting thing to track for those who are not taking hormonal contraception. Why do you need to not be taking hormonal contraception to utilize the heart rate feature for menstrual cycle tracking? Hormonal contraception suppresses ovulation, and ovulation changes our heart rate charts!
Heart rate in people who are ovulating is at its lowest point during menstruation, rises during the fertile window, and continues to be elevated in the luteal phase.
When heart rate begins to drop again, this is an excellent way to predict menstruation will soon occur. For example, I have been tracking my heart rate in Fitbit for 2 years, and I always bleed when my heart rate dips back down to 70 beats per minute after my luteal phase!
I do think this feature is worth tracking for anyone interested in a more precise period prediction than cycle length. If you have Fitbit premium, you can also find a setting for sleeping heart rate under restoration. This may be more steady than resting heart rate for some individuals.
Lastly, I want to address Fitbit temperature for menstrual cycle tracking. Unfortunately, wrist temperatures are not a compatible parameter for fertility awareness when it comes to avoiding or achieving pregnancy. It can be incredibly erratic. When we track temperature, we want the temperature as closest to the core as possible.
Fitbit does not give precise temperatures, instead it gives deviations from a range. I likely ovulated near 18, 19, or 20 on the photo above. While Fitbit did detect a slight shift, it is not particularly clear, and it dropped back down.
As depicted above, my luteal phase the previous month was extremely undefined, and I could not determine a confirmed temperature shift with it.
For now, I do not recommend Fitbit for precise temperature tracking. Instead, I recommend a basal body thermometer.
Fitbit offers some really unique options for cycle tracking, but it should not replace your birth control or fertility awareness method. The heart rate feature may be useful for identifying cycle phases, but the temperature readings are not suitable for tracking cycle phases.
I purchased a Fitbit device close to two years ago, and within months I noticed that my heart rate appeared to be correlating with the phases of my cycle. Now eighteen cycles into comparing my heart rate to other fertility signs, I can say with confidence that it has lined up every cycle. This shouldn’t be too surprising because we already know that progesterone causes basal body temperature to rise, but heart rate does not exactly follow that pattern.
We have known about the possible connection between heart rate and the menstrual cycle for over a century, but in the last 50 years a few studies have taken a closer look.
Palmero (1991) studied 64 women for 3 consecutive months and created a PMS group versus a non-PMS group. They found that “in the premenstrual phase, PMS group showed significantly higher resting HR levels than NPMS group.”
Moran (2000) followed 26 women and found that “resting-heart rate was significantly higher in both ovulatory (P < 0.01) and luteal (P < 0.01) phases than in the menstrual and follicular phases.”
Shilaih (2017) followed 91 women and found that they “observed a significant increase in pulse rate (PR) during the fertile window compared to the menstrual phase (2.1 beat-per-minute, p < 0.01). Moreover, PR during the mid-luteal phase was also significantly elevated compared to the fertile window (1.8 beat-per-minute, p < 0.01), and the menstrual phase (3.8 beat-per-minute, p < 0.01).”
I want to highlight these last two studies in particular, because many of the other studies have an issue. Marco Altino explains why:
“The great majority of studies looking at HRV and the menstrual cycle collected one single data point during the follicular phase and one single data point during the luteal phase. I don’t have to tell you how little sense that makes, considering the high day to day variability in these parameters.”
This is an excerpt from his blog on heart rate variability in the menstrual cycle. Read the full blog here.
The 2017 study published in Nature by Shilaih, et al found that heart rate may rise up to 5 days before ovulation occurs. This means that heart rate could potentially be a used as a way to time intercourse for conception.
My results are so steady with resting heart rate that I dream of someone using it in a long-term study with other fertility signs. Wouldn’t it be cool if we could avoid pregnancy using heart rate too?
Below is an example of my results with resting heart rate. To convert my heart rate to fit in a fertility awareness app, I use a conversion. Essentially, one heart rate beat = .1 Farenheit change on my temperature scale. A heartbeat of 69 becomes 96.9, 70 becomes 97.0, 71 becomes 97.1 This preserves the original ratio, and it allows me to show the data with other fertility signs. For your own conversion, you may model this. If you have a lower heart beat rate, you can still convert, but you may need to do an additional equation.
In conclusion, I believe that resting heart rate is a very unique sign to track, especially if you already use a wearable fitness tracker. I will note that a false heart rate rise can be caused by illness, alcohol or food close to bedtime, nightmares, and more! This is not dissimilar to what can obscure a temperature. I hope that in the future more studies are done so that we can see if heart rate can also be used for avoiding pregnancy purposes.

Have you ever wondered what it was like to chart with the Marquette Method? This blog attempts to give an overview of what it is like to chart with the Marquette method (monitor/hormones only) for one cycle. Since I am in regular cycles, this is only an overview of what that looks like. Postpartum charting involves a whole lot more testing!
Day 1: Record Heavy Bleeding.
(This is an available day for safe sex based on my Marquette calculation rule. Marquette calculation rules rely on the earliest peak in the last 6 cycles minus 6. For me, this is Day 7, with Day 8 being automatically the first “unsafe” possibly fertile day. Any time of day is allowed within Marquette calculation rules).
Day 2: Record Heavy Bleeding.
Day 3: Record Heavy Bleeding.
Day 4: Record Medium Bleeding.
Day 5: Record Medium bleeding.
Day 6: Do absolutely nothing! My testing window opens on Day 8.
Day 7. Do absolutely nothing! My testing window opens on Day 8. This is my last day to have sex pre-ovulatory per the rules of the method.
Day 8: I wake up at 6:30am, pee in a cup, dip the stick for 15 seconds, and wait 5 minutes for the Clearblue Monitor to read my test. I get a “L” or low estrogen reading. The Clearblue monitor reads both estrogen and luteinizing hormones.
You can use any time within a 6 hour range to test using the monitor. I’m just rigid because I have an alarm set!
In Marquette, you set a 6 hour testing window to take your test in that is determined at the beginning of each cycle when you trigger a new cycle start date on the monitor. I usually do my tests with first morning urine when my alarm goes off, but I could do it later in my testing window if I desired.
Day 9: I wake up at 6:30am, pee in a cup, dip the stick for 15 seconds, and wait 5 minutes for the Clearblue Monitor to read my test. I get a “L.”
Day 10: I wake up at 6:30am, pee in a cup, dip the stick for 15 seconds, and wait 5 minutes for the Clearblue Monitor to read my test. I get a “L”
Day 11: I wake up at 6:30am, pee in a cup, dip the stick for 15 seconds, and wait 5 minutes for the Clearblue Monitor to read my test. I get a “H” or high estrogen reading. This means that my real fertile window is likely opening and ovulation could be around the corner.
Day 12: I wake up at 6:30am, pee in a cup, dip the stick for 15 seconds, and wait 5 minutes for the Clearblue Monitor to read my test. I get a “H.”
Day 13: I wake up at 6:30am, pee in a cup, dip the stick for 15 seconds, and wait 5 minutes for the Clearblue Monitor to read my test. I get a “H.” Based on having high quality mucus (which is not required to notice for monitor only), I crosscheck with a LH test because I know ovulation is likely approaching soon.
Day 14: I wake up at 6:30am, pee in a cup, dip the stick for 15 seconds, and wait 5 minutes for the Clearblue Monitor to read my test. I get a “P.” This means the monitor has now detected my LH surge. I crosscheck this same urine with another LH cheapie test, and it is also positive.
This means I have peaked for the cycle! All other readings after the “P” are automatic, and I do not have to take any other tests. Marquette requires me to meet PPHLL before resuming intercourse on the day after the second L.
At this point, if I desired, I could be done charting for the whole cycle! This means that I only had to really chart for approximately 7 days this cycle. How easy is that?!
If I desire, I could also take a Proov progesterone test around the second L at the end of my count. This would provide proof that the hormone progesterone has taken over.
Some of the downsides to this method could be:
The Monitor missing peak (it happens! You may want to keep cheap LH strips on hand for back up, or cross check with temperatures).
The Monitor will not tell you if you are going to ovulate early. The only way to detect earlier ovulation is to track cervical mucus very carefully.
The sticks are approximately $1.50 each. This could get very pricey for delayed ovulation!
The method may not be appropriate for people with very irregular cycles
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 Marquette in a regular cycle. I recommend finding an official Marquette teacher here. Because the Marquette method uses the Clearblue monitor which is designed for trying to conceive, you will need to get instructions to use this monitor for avoiding pregnancy.
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.
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.
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.
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
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.
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.
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.
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.
In this blog, I’m going to refute some of the arguments against fertility awareness. At the risk of losing some of my audience immediately, I have included the word feminist in this blog title. A while back, I got into an argument in a Facebook comment section with someone who was offended by this article that questioned the pill and it’s effect on women. The argument went nowhere fast, but it got me thinking.
In many circles, questioning the birth control pill is tantamount to attacking women’s rights. I have been told that I’m not a good feminist if I don’t support the pill. As someone who fully supports women and their choices, and as someone who only wrote about women in my graduate degree (I did a lot of gender studies topics), this assertion really hurts.
I know that the birth control pill changed many people’s lives. It brought women into the public sphere more than ever before. Women could now work and have sex without fear of pregnancy. It is considered a great achievement. What’s better than that?
The problem is that not many women are not fully informed about what their birth control options are before being put on the pill. In addition, women are put on the pill for reasons other than birth control (things like heavy bleeding, endometriosis and PCOS). However, we now know there there are alternative forms of birth control, and that the pill does not treat gynecological conditions (it masks them).
I was put on the birth control at age 15. I suffered from heavy bleeding, and mostly my mom just wanted me on it out of pregnancy fears. My doctor did not give me any information about the pill or expected side effects. (Some may point out that the packet comes with information, but freshman year aged me from high school did not think to read my birth control pack in depth). I was switched between at least 4 different types of birth control that I remember. The pill gave me migraines with aura (which I recently learned means I should have gotten off of it immediately, there is a link with having a stroke and migraines with aura while on the pill). I would lose vision while at work and had other disturbances in my vision. I also had pretty regular nausea, weird bleeding, depression, and digestive issues.
When I came off the pill for the first time at age 21, everything felt different. My emotions felt different, and my relationships changed. However, I was left with little alternatives for contraception. To me, taking the pill had become synonymous with being responsible, and I felt like I was failing at being a responsible woman and controlling my fertility.
At the same time, I felt so great coming off of it that I knew it wasn’t an option for me any longer. I felt truly like myself for the first time. One line in particular from a short film called Birth Control Your Own Adventurereally resonated with me. This film is about how one woman struggles to find the right hormonal birth control. At one point a friend asks her, “How do you even know who you are if you’ve always been on the pill?” And, truly, I don’t think I knew myself while I was on it.
In my search for a better birth control, I stumbled upon fertility awareness methods. I found out that it was possible to track my cycle and determine daily whether I was infertile or infertile. Charting my cycle helped me learn when to expect a period. I had no idea that you could literally count high temperatures after ovulation in order to know when to expect a period. This feeling felt revolutionary, and I wanted to tell everyone.
When I try to share the joy I have found in this method, I often hear a few retorts. I’ve listed a few below along with my responses to these arguments.
The Arguments Against Fertility Awareness
Why should I have to plan sex? It seems kind of sexist that you expect women to wait to have sex at certain points in their cycle. On the pill, I can have sex whenever I want.
With fertility awareness methods, you don’t really have to “plan” to have sex. You can, however, choose to have unprotected sex during the infertile times of the cycle. If you are using a secular form of fertility awareness, you can also use condoms or other barriers during other points of the time in the cycle (keeping in mind that these barrier methods have their own efficacy rates).
I think it’s also worth noting how often the average couple has sex. A 2017 study found that the average American couple only has sex once a week. My window for abstaining or using backup protection is only about 9-11 days long. That’s a little over a week and a half a month. (I’m aware that some women have longer fertile windows. This aspect of fertility awareness is very individual and based on your own unique cycle). So, are these women really missing out on having unprotected sex a little less often?
Finally, yes, you can have sex on the pill whenever you want. However, the pill has been known to lower women’s libido and testosterone. Read this article to find out more. So, while you can have sex any time you want on the pill, doesn’t quality of sex matter? You can still have sex pretty often while using fertility awareness, and you may find you enjoy it more too.
This method seems really irresponsible. It only takes one time for a woman to get pregnant. What if she decides to have sex in her fertile window?
If someone is fully informed and taught by an instructor, they will know when their fertile window is. Yes, it only takes one time to get pregnant but if you are using fertility awareness, you know when that window is. If she decides to have sex in her fertile window, she may consider a barrier method. Anyone who has sex during their fertile window should be cognizant of the risks of pregnancy. By the way, at a typical use rate of 91%, someone could also have sex in their fertile window without knowing it while on the pill. At least fertility awareness lets women know what is going on in their own body.
Isn’t that a super religious method? I don’t care for that. It’s my body and I can have sex when I want.
Natural Family Planning is based in religious teachings. Fertility Awareness is not. Women can pick what they feel comfortable with based on their intentions. You can also still learn from NFP resources even if you aren’t religious. The method works the same regardless of any ideology attached to it.
Isn’t that like the rhythm method? You can ovulate at any time!! That’s not gonna work!
No, it’s not. There are many scientific studies on fertility awareness. Here is one. Here is a recent article reviewing all the studies done on FAM.
Women cannot ovulate at any time. Once ovulation has been confirmed in cycle, it is almost totally impossible for it to happen again. Some people say, “What about superfetation??” This is so rare, and almost impossible to prove. If you are confirming ovulation with a double check method, then you can be safely assured that ovulation will not happen again. At the beginning of a cycle before ovulation is confirmed, it could happen at any time. However, there are rules to follow so that women know when to stay protected.
The typical use rates of fertility awareness (when abstinence is practiced in the fertile window) is higher than the typical use rate of the pill. See my about section for more information.
But women need the pill for medical conditions, you know like endometriosis? Do you want women to suffer?
Obviously, I don’t want that. What’s important to know here is that the pill doesn’t actually treat endometriosis, or PCOS, or anything else really. It just masks the problem. If you have extreme period pain, you need expert care. The pill may mask problems that would eventually hurt a woman’s health and fertility. In particular, I want to note that if you are suffering from endometriosis, there is help. Join Nancy’s Nook Endometriosis Education to learn what your options are. For PCOS, Alissa Vitti is a great resource. Here is her website.
Isn’t it kind of anti-feminist of you to promote this? Women should be able to control their fertility however they choose.
Ah, my favorite question. I do agree that women should be able to control their fertility however they want. My whole shtick is that they should be fully informed in order to make this decision. With the dearth of good sexual education programs in the USA, almost no one is informed enough. Even doctors aren’t informed enough. Many only take one measly birth control class. Fertility awareness instructors do more than that, and they aren’t even in medical school. If more women knew that fertility awareness methods actually worked, they could make the decision to learn more about their body. I believe that all women should learn about fertility awareness methods as soon as they have their first cycle. It is so useful for girls to know what’s going on in their bodies!
I also argue that we have a #righttoovulate. I saw Dr. Lara Briden post this hashtag a while back, and I love it. Ovulation is amazing. And actually, I think it’s sort of anti-feminist to take that away from women, especially if they don’t understand what they are missing. Women are only fertile for around 24 hours a cycle (men’s sperm life makes up the rest of the fertile window). This is such a small window. Don’t we deserve the benefits of ovulation? Read Dr. Lara Briden’s article, “Ode to Ovulation” to learn more. In addition, some people have argued that it takes 7 years to develop fully healthy hormonal cycles, shouldn’t we be able to do that too? Putting women on birth control when they are young prevents so many of those benefits.
**I will note that I understand that hormonal birth control can be invaluable in domestic violence situations, or when a woman really cannot do FAM, or is forced on HBC for unrelated medical conditions. I just want the average woman to know that she has other options.
Most of the arguments against FAM are from uniformed people who don’t know what they don’t know. Fertility Awareness is actually feminist, and it’s certainly not anti-woman. It allows women to take control of their own fertility (here’s a great book on that). What’s more feminist than fully owning and living in your own body, while also avoiding pregnancy and planning it as you choose? Why should women subdue their own fertility when their fertile window is so short?

I always have trouble finding charts without temperature scales. As someone with lower temperatures than average, the standard temperature scale just doesn’t work for me. These charts have totally blank temperature scales. They will work for F or C charting.
I also included a page with space for cycle notes, method rules, and legends for certain things on the chart.
