I had a boyfriend and we were sexually active. I think we had sex on April 20th and the next day broke up.. don't judge but I then slipped up and had sex with a different guy on April 26th and ever since that day I have been having a lot of brownish color discharge and my boobs have been kind of itchy. The discharge doesn't smell like anything and my lady parts don't itch or burn or anything.. I am a little embarrassed to go to the doctor though. I usually start my period around the 10-20 of the month.. I am 20 about to be 21 and I am just wondering what it could be..
