Typically, progesterone levels peak five days after ovulation and then decline. A progesterone test performed seven days before your next period is due can identify whether or not you have ovulated. If ovulation didn't happen, your progesterone levels will be lower than expected. If you become pregnant, your progesterone levels will continue to rise.
If you're planning a pregnancy, healthy progesterone levels are essential to prepare your womb lining. Therefore, our test is a helpful first step to look into your fertility.
