Hi, I experienced red spotting two days after protected sex. I just began having sex only a few months ago with my boyfriend. About a week and a half ago I was diagnosed with a bladder infection and I just ended my medication. My boyfriend and I had sex twice in one night and once the next morning. We use a condom and pulling out to stay safe, but during the morning we were having rough sex the lubrication on the condom diminished. I don't know if the bleeding is because of the bladder infection, the loss of lubrication, both, or because of something I contracted. Thank you for your time!
