Progesterone is usually high during:

• A. Menstruation period
• B. 14-15 days
• C. 21-23 days
• D. 5-7 days

Answer 1

Answer:

C. 21-23 days

• Progesterone levels increase in the luteal phase, which help thicken the lining of your uterus.

• The increase in hormones: Prepares your uterine lining for pregnancy by making it thicker.

• The thick lining is the ideal environment for a fertilized egg to implant (attach) and a pregnancy to grow.

• After the egg is released, the follicle left behind in your ovary releases a large amount of progesterone.

• When you undergo Day 21 testing (approximately 7 days after ovulation), your doctor should see a surge in progesterone.

• A high Day 21 progesterone level indicates ovulation and the release of an egg.
