... tuedsay pill (meaning 3 pills in one day) then I was put on a Z-pack the next week and she didn't say use backup method or anything so we didn't and had unprotected sex every day pretty much. Oh, and If I ovulate, I would have been doing so that week as well. I've been having really sore breats and cramps for a few days but my period is due next Tuesday. I've been on enpresse-28 oral for 2 years now too btw. What are the chances that I'm pregnant?
