So It was a couple days after I just got off my period. I started my period 12th of September and I got off that Friday the 16th and me and my boyfriend had sex that Sunday and we had the condom on, but it ended up breaking. He didn't know and a couple hours later we went to the Pharmacy and bought Plan B, I took it maybe 3 hours later and it has been the 3rd day now. I'm scared, because I just had my period this month usually I get my period around the middle of the month. I'm just experienced some tightness bellow my belly button. Can someone help me pleaseeeeee?
