So I had sex on my birthday and I haven’t had sex in 3 months, when I haven’t for a while it gets a little tighter to enjoy it but I used lubricant condoms and lube. This happened on the 11th and I’m not ovulating so I checked my calendar on here and it says my period is supposed to start in two days. Sometimes it will start a day early. I’ve had brown discharge since and it’s not itchy or anything. I had just a little discomfort for a little bit but it went away sometime yesterday. I don’t think it’s pregnancy because we used a condom and the guy I was with had erectile dysfunction so he didn’t even ejaculate the whole time we we had sex. Is it old blood or is it that my cervix got a little irritated?
