Each Proov Predict package includes 30 LH tests (enough for 2+ cycles), plus a convenient P-cup.

You’ll test your pee twice a day as directed to make sure you catch your most fertile window.

Proov Predict measures luteinizing hormone (LH), a marker in urine that tells you ovulation is about to occur. Identifying an LH surge helps you zero in on your two most fertile days, so you can try to conceive at the best possible time.
