I'm 16, female, I had tonsilitus 2 weeks ago and was on penicillin which led to itching, irritation, odd discharge from my vagina. last week I had my period and now I am having brownish clumpy discharge, itching and a lot of pain. Also little red raw bits. In the mornings there seems to be a layers of white stuff between my labia which comes off when touched. Any idea what's wrong?
