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!!
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.
