What Are Normal Progesterone Levels After Ovulation?

There are no normal ranges of progesterone levels on this subject after ovulation. The progesterone on this subject blood level depends on the time of the exam and phase of the pregnancy cycle. Progesterone is a hormone that is released after a woman ovulates. For example, levels may decline by 50% after eating and change from morning to night. A blood test result should indicate levels of between 10-12 ng/ml for a pregnant woman.

Progesterone deficiencies may trigger a miscarriage. The hormone is important in pregnancy, because it signals a woman's body to thicken the uterus walls and lining in preparation for pregnancy. This means that the egg has been fertilized and within 48 hours will develop into an embryo. The embryo must attach itself to the uterus wall.

In cases where the embryo does not successfully attach itself to the uterus wall, the woman is at risk of miscarriage. This is why hormone testing is important for women. A doctor will recommend supplements based upon the blood test results.
