Is it possible that I could be pregnant if I’ve been use the ortho-evra patch form of birth-control? I followed the instructions correctly and I am about to start my fourth cycle of patches. However, I haven’t had my period after I went off my third patch for my third cycle. I did, though, get breakthrough bleeding as they call it for about a week aroudn the time I started using my third patch. Could that have been my period, just a week early? I have been having cramps for about three days now but haven’t gotten my period. I’m not sure if it’s all stress (i’ve been dealign with a huge family/boyfriend situation for the past month and school) or I’m just insanely paranoid. please help!
