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

Proov Confirm uses a patented testing method to provide the most thorough understanding of ovulation quality by measuring PdG. You’ll assess PdG levels multiple times throughout the second half of your cycle (the “implantation window”), gaining valuable insight into overall ovulation quality.
