last year i thought i was have my period, but it was not. i found out i was bleeding from Aug. to Jan. of last year and did not stop and when i went in for surgery i was only 79 lbs. and when i got out of the hospital i was 81lbs. then dropped to 71 lbs. and now i'm 77 lbs. and i'm still trying to gain weight. but i can't seem to gain any weight back.
