i had to leave work last night, for some reason i felt a sharp pain in my left side and i started bleeding very heavily and bled througha super tampon each hour i was there bleeding through 3 different outfits. pain only lasted about a minute and now i have no pain. i called the doctor and she said if the bleeding didnt slow down i should go to the hospital, she didnt explain why i should go. i thought maybe it wwas just a heavy period, but never in my life have i bled so much. im haveing little clots too. could it be because i didnt finish the doxycycline antibiotic ? infection? what could happen? This bleeding needs to stop now!!!!! help me please.
