... patch would not stay on, so i replaced it within the 24hr gap and again it would not stay on therefore i stopped using it all together. I stopped on the tuesday and the change day was friday. i had unprotected sex a couple of days after i stopped using the patch and my boyfriend came inside of me. I started bleeding on the saturday which i assumed was the withdrawal bleeding even though i hadn't completed the entire cycle, however, the bleeding was heavy for three days and now I've been spotting for about 3 days. Should I expect my normal period which is due 2 weeks from now or is this abnormal bleeding? Or could i be pregnant?
