I am a 22yr old with PCOS. I have been on the Xulane birth control patch for about a year now, ive never had any problems other than just very high flow periods. During this specific cycle of the patch I put the first patch on, on time, and took it off on time. But I put the 2nd patch on a day late by accident, I also changed the place i normally put the patch. After about a few hours of wearing the patch i started getting cramps and a day later started bleeding. I have been bleeding for about a day now and im still wearing the patch. Im not sure whats going on, what I should do or if it was my fault or not. Can someone give me any answers???
