I was period-less for 6 months straight & went to the doctor checked out my thyroid, etc. progesterone levels came back really low. I got 10mg progesterone pills for 10 days got my period finally on December 13th it wasn't a heavy flow which I thought it would have been. I was using progesterone cream for a few days (6) not sure if the cream will have the same effect the pills did. Trying to concieve. Feeling hopeless.
