amenorrhea
"I am 22 years old and I took Provera for 10 days twice a day starting March 7th. 10 mg.  It worked for me. About 5 days after I ended the Provera , (3.22.11), my period showed up. I am trying to conceive with my fiance but first I need my period under control. I hope this all works out. So far so good. "
