Hi I have pcos since age 15 and now I'm married, trying to conceive. My periods were never regular since menarche. For the past 3 years I have no natural period cycle. I take progesterone tablets like meprate/ duphaston/ provera to get withdrawal bleeding. There are times when I didn't get periods for almost 7 months. I was very lean .now I'm 60kgs and 153 cms. 3 iuis done for me. Got 2 times pregnant but both ended in miscarriage (chemical pregnancy and one dnc done ) Does taking progesterone tablets as part of treatment affect body ? Does that cause cancer in uterus in future?
