So I had sex over the weekend and noticed I was unusually dry. I've actually been pretty dry lately but I think that might be because of the birth control I started taking. Anyway, the entrance to my vagina has been kind of itching, and when I looked with a mirror I saw an unusual discharge. It's white and looks like it has chunks of torn up toilet paper or like it's kind of chunky. I smelled it and it doesn't have any fishy odor or anything. Could this be a yeast infection? This has never happened to me before. Also, I take tri-sprintec and I read that one of the side effects can be yeast infections.
