Okay. So I have been having vaginal issues. It all started after I had sex with my boyfriend, it was protected sex. But now I have a itching sensation of the vulva and ammonia smell. It isn't always itching, just randomly it will itch. I just recently started getting a light yellow, snotty discharge and also a burning sensation when I pee and even when I am just sitting there I'll start feeling it. Me and my boyfriend have never had sex with anyone else, where each others first so I'm not thinking it has anything to do with std's but I'm still not sure. Could it be BV?
