amenorrhea
"I'm 18 and had very regular periods every month for 4 years and they stopped for no reason. Played the wait game & before I knew it 3 whole years has passed. 5 day 10mg provera challenge starting July 1st and on July 9th, 4 days after my last pill got my period. Not a terrible period for me like everyone else. A little heavy, mild cramping but my periods use to be worse. Also, does anybody know if it's true if my periods come back on their own after 3 provera cycles? Read that a few places but idk if it's true."
