I have been trying to find information about normal progesterone levels.
I am currently on Clomid (month #3).  The first month, I appeared to ovulate
and had a progesterone level of 16.  I did not ovulate during the second round
so took provera and began Clomid again.  This month, my progesterone level
was 30.6.  I understand that it is good to have levels >15 but does it mean
anything when it almost doubles?  What are the typical upper ranges for
progesterone?  Also, are progesterone levels good indicators of pregnancy?
Thanks for your help!!




DearAlyssa:
In the luteal phase, a progesterone level >10 ng/ml is normal. Some people make the level slightly higher (12 ng/ml) when using clomiphene. In early pregnancy, the level is expected to be above 15 ng/ml.
There is no upper limit on progesterone. The level is higher with multiple pregnancy, it rises progressively as the placenta grows, and near the end of pregnancy, 250 mg/day is being produced.
Progesterone is not a pregnancy test. Progesterone is produced both during the menstrual cycle and during pregnancy. The level of progesterone, when above 15 ng/ml, is associated with a normal pregnancy but it does not assure normality.

Are there typical upper ranges for progesterone if you are not pregnant?
