I lost my birginity on 12th March, we didnt use a condom (STUPID!! but trust boyfriend 100% and he had STD test recently) Had to take Levonelle Morning after pill. Then went on the Yasmin BC pill. Havent been using condoms for various reasons. (Please dont tell me to or judge me, thats not what I need advice on)

But since then I have had occasional dryness to the point of discomfort, occasional thick brown discharge and occasionally I cant fully empty my bladder when urinating and it sometimes burns.

I know 100% that he had a STD test 3 months before I was with him, (good friends first) and it was negative. I know he wouldn't cheat or lie. But his ex gf cheated on him quite a bit, he has/had no symptoms of an STD but I'm worried that she caught something and passed it to him and now I have it and he doesnt know he has it. I also sometimes get burning and itching.

I dont know what it could be, but I'm scared.
