Progesterone - Day 21

Examine your progesterone levels.

Understanding the benefits of testing your progesterone levels is crucial, especially if you have inquiries about fertility. Identifying whether or not you are ovulating is a fundamental starting point.

When ovulation occurs, there is a significant rise in progesterone levels at approximately day 21 of your cycle - or 7 days before your expected period if your cycle is irregular.
