Proov tests check levels of the hormone metabolite PdG in the urine. Proov tests are an FDA approved product. People who are ovulating produce the hormone progesterone after ovulation. If you are a fertility awareness charter, you can use these tests to double check that ovulation has occurred along with your other fertility signs. If you are seeking to become pregnant, you can use these tests to help see if your luteal phase is sufficient to support a pregnancy.

I have personally been using Proov since 2018. It is a regular part of my fertility awareness routine that I use to avoid pregnancy. But the main reason people use Proov is to help achieve pregnancy!
My most common day to get my first positive Proov is approximately 3 to 5 days after a positive LH test. I love having Proov as a crosscheck so that I can have an extra way to confirm ovulation. I like having a ton of data in my fertility awareness routine. While there is currently no official protocol for confirming with Proov tests (outside of Marquette method tentative guidelines), you can use them as a part of your fertility awareness routine regardless of your intentions. You should still rely on the fertility signs in your method rules while using Proov.
For those trying to conceive, the tests can be used around 7 to 10 days post peak fertility as based on a positive Luteinizing Hormone (LH) test. If the Proov PdG tests are positive on at least 3 out of 4 of these days , this is a good sign that your progesterone is high enough when implantation is most likely to occur.
These tests are also useful for people with irregular cycles or tough cervical mucus patterns because they can help you know if you have indeed ovulated.
Proov also has an app that can help you read your tests, including LH tests. It recently updated to include numeric values. This makes the data even more meaningful! Some people struggle reading Proov, and the app is definitely useful for those people.
Update September 2021: The new Proov Insight app has been updated to include an ovulation score based on inputting 4 Proov tests. I tried it this cycle!
I used the new Proov LH strips in the app. It read the LH tests for me (so easy!).
Then, at 7 to 10 days post peak fertility, I took a Proov Pdg test each morning. All but one were positive, and the negative one was very close as you can see below.
I highly recommend trying Proov if you are curious about your progesterone! For now, I have decided to make Proov a permanent part of my avoiding pregnancy fertility awareness routine.
