I change my patch on Thursdays. So I was supposed to change my patch last Thursday(9/25/14) but I didn't because I didn't have anymore and had to order more patches. So I didn't get my patches until the following Monday(9/29/14). So I went 4 days without wearing a patch. But when I got them I put them one on that Monday as I normally would if it was Thursday. I didn't have sex on Monday, but I did have sex on Tuesday and my husband ejaculated in me. Then Tuesday night, at around 3 in the morning, I got up to go to the bathroom, and noticed that I was bleeding? Am I getting my period, since I went 4 days without wearing a patch and my body thinks its time for my period? Should I keep my patch on or take it off? Can I get Pregnant?
