On last Sunday I had sex with my boyfriend and I haven't sex in like 3 years , but while during the sex I was bleeding a little , so I guessing that's normal because haven't had sex in a long time. We did used a condom at first but we decided to take off... The next day I start to see a yellow discharge so I smelled it but it didn't have an odor , I'm itching or irritated. I also take birth control pills , I just some advice to do right now.
