I am having 2-3 Menstraul cycles a month. I am also having very sharp pains inside my vagina. I just recently saw a gyn on 3/30/09 and the dr wasn't able to tell me what was wrong. I was scheduled for my pap that day but was bleeding. She tried giving my the pap because i informed her of my pains. She wasn't able to do the full exam but was able to test for a couple std's and didn't find anything abnormal. I have never had an abnormal pap. I am also have noticed that my discharge has been thinker than usual and slightly brown. My cycles last anywhere from 2-7 days and are light to medium (sometimes heavy but not usually). These pains are very random and last anywhere from a couple seconds to 30 mins. Some are sharper pains than others and it hurts to make any kind of movement when they occur. My mom thinks I may have cervical cancer.. but since i haven't had an std is that possible? What could be causing my pains, thick/brown discharge, and irregular bleeding?
