Help ah

Ok so the other night this guy and I were super drunk and had unprotected sex but i'm on the pill and he pulled out. I bled a lot during it and now the next day I'm getting a little of a fishy smell and white/ yellow discharge. I looked and besides some discharge in there everything looks normal. There is no itching, burning, or soreness though. What's up with me??? I'm not uncomfortable, just worried about Trichomoniasis.
