I'm 18 turning 19 with a regular period and usually normal white discharge before my period. I noticed recently that it has turned a greenish color. I've been with my boyfriend for almost a year, and we occasionally have unprotected sex. I also have a history of urine infections. Not sure if that has anything to do with the discharge but I noticed it occuring after a recent, minor urine infection that was treated by medication. There's no itching and no irregular odor, but often this discharge when I wipe, or yellow discharge that crusts in my underwear..it's pretty embarassing. I've done some research and learned a little about Bacterial Vaginosis?..I'd like to get it checked but it's hard to keep it from my mom, I don't want her knowing im sexually active..
