Hi there, I am on the Evra Contraceptive patch which Iv been using correctly and always changed my patch around the same time. I just got out of a relationship 2 weeks and before we broke up we had unprotected sex and he came inside which I think was before the 15th of November. However I had unprotected sex a week ago with someone else on the 28th Of November and was still using my patch correctly and we only had sex for a couple of minutes and he didn’t cum inside. But for the past couple of days from Tuesday the 3rd I had brown discharge and when I wipe it is a little brown which has been on and off and I have a little cramping, lower back aches and nipples are sensitive. I am due to take off my patch on Friday and period would normally come Monday/Tuesday. Could I be pregnant? And to who
