Common Questions

How do pms or pcos symptoms affect ovulation?

PCOS (Polycystic Ovary Syndrome) can cause irregular cycles, making it hard to predict ovulation without using lh tests or bbt tracking.

What is lh?

Luteinizing hormone (lh) peaks 24-36 hours before ovulation. You can detect it with an at-home test.

Is keeping a menstrual diary useful?

Yes, logging your symptoms, bbt, and period dates helps you track your fertility and detect early pregnancy.
