I used it along with
Femara, did not conceive, and felt horrible the entire second
half of the month. I was exhausted, my breasts stung, and I was in a horrible mood. Previous to using progesterone cream I have never had a PMS symptom in my life. This month I decided not to use the progesterone cream but continued the Femara. I felt sure that I would get a positive test because I felt even worse than last month, but sure enough I got a negative pregnancy test and my period came.
