amenorrhea
"I was prescribed Provera (10 mg/ 10 days) due to not having a period for several years and so my husband and I can have a baby. Works like a charm. Started period 4 days after taking last pill. 1st day was mild flow and all subsequent days were extremely heavy. It's now day 6 of having a period, which is not normal for me even when I had periods, and continue to have extremely heavy flow. I will be calling my doctors office today as I do not want this to continue. The upside is I did not experience any side effects while taking the medicine."
