... patch(4/30/15) I never put a new patch back on for that whole week, so I had my patch off the 4th week of my cyle which I was supposed to and an extra one. I had unprotected sex both weeks. I put a patch back on 05/11/15 and took it off today 05/14/15 due to the facts that I also switch to the depo-evra shot. Is there any possibility I could be pregnant? I did get my period my last off week so since I was on the patch I didn't ovulate right?
