ok...i'm 19 and i lost my virginity a day ago. Everything was normal until after sex, when i started bleeding uncontrollably. I lost ALOT of blood and my boyfriend rushed me to the hospital. The doctor couldnt find any cuts and she concluded that the problem was in my uterus. She did, however, find alot of clots in my vagina. I have irregular periods and a while ago i checked that out and my doctor recommended an ultrasound but i didnt take it as yet. The doctor at the hospital also recommended one. Did the sex cause that problem or trigger it off somehow? Has this ever happened to anyone before? It was so bad that i had to go on drips. Presently i am still bleeding but its as though i have my period. Is it possible that a number of clots could form again? I do have intentions of taking the ultrasound sometime this week.
