Progesterone Day 21 (Ovulation) Blood Test

The ovulation (day 21 progesterone) blood test is a simple test used to check your progesterone hormone levels. The ovaries produce progesterone hormone after ovulation, and it helps to prepare the uterus for pregnancy. This test is typically done on day 21 of your menstrual cycle, but it can be done earlier or later when necessary.

The results of the progesterone day 21 blood test can provide insights into fertility issues, such as identifying the optimal timing for conception or detecting any potential problems that may affect a woman's ability to conceive. It is often used with other fertility tests to assess overall reproductive health and develop an appropriate treatment plan.
