I had no side effects after taking provera after my D&C. My period started about a week after I took the last pill. We were able to start trying again once I started. I did notice my period was lighter than normal-other than that, no side efects.
I am in the same boat I will start it next week if i don't have a period between now and then, i have taken it in the past and i didn't have any side affects after I had my son everything went back to normal more so then before
