I am 17 yrs old and I am a lesbian. The other night I had intercourse with my girlfriend using a dildo. The next day, whenever i would urinate i would have SHARP shooting pains all threw out my vagina, and a large clump about the size of silver dollar, lite brownish with spots of blood would come out of my vagina. Kind of a mucus look to it. This went on for about a week. My mother is a certified EMT and told me that I had to rough of sex and it was the lining of my uterus. Any help on the situation? MUCH NEEDED!! ? ! ? :-( :$
