Find Your 2 Most Fertile Days
When it comes to getting pregnant, timing can play a big role. Whether you’re timing intercourse or insemination, Proov Predict identifies your 2 most fertile days so you can do so with confidence. Plus, our free Proov Insight companion app makes it easier than ever to know when to test, interpret results, and help you plan the best next steps to help you get pregnant faster.
Unlike what high school sex ed taught us, there are only a few days each month when it’s possible to get pregnant. Proov Predict measures LH, the hormone that spikes just before ovulation and tells you exactly when to “try.”
You’ll start tracking your peak fertility with Predict tests about 18 days before your next expected period. We define “peak fertility” as the first positive LH test, not the “most positive” like some other brands. Once you get your first positive test, you can stop testing.
Please refer to kit instructions for specific details.
Tracking LH (luteinizing hormone) levels during the first half of your cycle can help you detect an LH surge, which indicates you’ve reached your two most fertile days (also called “peak fertility”). This is the time to “try!” During the first half of your cycle — the “follicular phase” — your follicles mature in preparation for ovulation. When the time is right, your brain sends a surge of LH (luteinizing hormone) to trigger the mature follicle to release an egg. Ovulation typically occurs about 12-48 hours after an LH surge.
LH tests are often called “ovulation tests,” but contrary to their name, they do not confirm whether or not you’ve ovulated; they only detect the luteinizing hormone surge that typically precedes ovulation. We recommend using Proov Confirm PdG tests alongside your Predict tests so you can confirm whether or not ovulation was successful to allow for a higher possible chance at pregnancy.
No — you may use Proov Predict at any time of day. The Proov Insight app will prompt you to test two times per day during the LH testing phase. Many women find it convenient to test LH levels mid-morning and again later in the evening, but the choice is ultimately yours.
