Below are some facts regarding progesterone. I hope that this answers your question.

What does progesterone do?

  • Helps to regulate the menstrual cycle.
  • Prepares the lining of the uterus for implantation.
  • Keeps the lining of the uterus thick which is necessary for a successful pregnancy.
  • Produces a rise in temperature after ovulation, which remains until menstruation occurs.
  • Creates a nutrient rich environment for the baby by increasing glycogen and arterial blood to the lining of the uterus.
  • Keeps the uterus from having contractions.
  • Causes the cervix to thicken and create a mucous plug which prevents bacteria from entering the uterus.

What are normal progesterone levels?

Progesterone during menstrual cycle

Day 1-14 

 >1 to 1.5 ng/ml

Day 15-28

2-28 ng/ml

Progesterone during pregnancy

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

Sometimes doctors will check a woman's progesterone level during pregnancy.  Most doctors like to see a minimum level of 10 ng/ml during the first few weeks of pregnancy.   If a woman has low progesterone levels this can be an indication of a threatened miscarriage.  If you are concerned about your progesterone level talk to your doctor for more information.
