I’m not a doctor, but after 4 pregnancies (1 was a miscarriage), I’ve learned a lot about the things that come with.  For example…progesterone…

What Is Progesterone?

Progesterone is a hormone that is produced by a woman’s ovaries to help prepare the uterus for pregnancy (it does other things in non-pregnant women).  In pregnant women, it creates a nutrient-rich environment for the baby by producing glycogen and arterial blood to the lining of the uterus.  Progesterone also causes the cervix to thicken and create a mucous plug which prevents bacteria from entering the uterus.

Progesterone Level Chart

(Progesterone During Pregnancy)

First Trimester: 9-47
Second Trimester: 17-147 ng/ml
Third Trimester: 55-200 ng/ml

*Most doctors like to see a progesterone count of 10 or above during the first few weeks of pregnancy.  Low levels may mean an impending miscarriage OR that your dates are wrong/things got off to a slow start.  If your levels are low, you will likely have a repeat blood draw in 48-72 hours to track your progesterone and hcg levels to make sure they rise appropriately.
