Hi, my question is just a concern...I ended up with an STI and it was treated and all the symptoms went away and I recently had sex again and ended up bleeding during it and now, the next day I have a pink/yellow discharge. Could this have to do with the STI I previously had or is it common? I don't have the symptoms of an STI again and the discharge isn't watery like it was with the STI, it's a mucus type, also my period is due in one more week if that's important to know.
