*doctor's opinion please* Normal female secretion changed to brown, thick discharge during sex? My girlfriend has sporadic periods, pelvic pain, and sex is occasionally painful. Sometimes during sex, I just notice the secretion has thickened and darkened. It's odorless, but not transparent. I highly doubt it's a yeast infection because there is no swelling or change in the taste of the secretion. I'm a female myself, I know what a normal (for me) brown discharge looks like and that it normally occurs before or after a period. This doesn't seem like the same type of discharge. More relevant information, she is a young adult and not pregnant. I doubt it is an infection because I have no symptoms and we've been sexually involved for over three months now. She thinks it may be from a tear causing bleeding. That or, I accidentally hit what I'm assuming is her cervix a few days ago that had caused temporary bleeding. If it wasn't her cervix, I'm wondering if it could've been a polyp. It was about four inches into her vagina. I'm probably just overly concerned and the discoloration was due to a little blood but the thickness and nontransparecy seems abnormal.
