The specific timing for your baseline test will vary depending on which Proov test kit you’re using and which cycle phase you are in when you begin using Proov. Once you upload your basic cycle data, your “My Day” home screen in the app will tell you which test to take, and when. It’s essential to follow the instructions carefully to get the full benefit of the Proov system, so please check your app daily and follow the prompts. If you have more questions about baselines, you can always contact us at info@proovtest.com.
