Hi, I have been on birth control for a couple of months now (about january/february). About 3/4 months ago i switched to a stronger prescription temporarily (2 months) and then went back onto my normal birth control. For my normal birth control i am supposed to start day 1 on the first day of my period, however my doctor told me to just finish the stronger pack and then go back to my normal birth control. Is it possible i delayed my period by not taking it on day 1? I havent missed a day at all, but i got my last period on october 17. My boyfriend and I have only had sex a small amount of times, 5 or less and always use a condom or pull out extra early but I still have no gotten it. Could i be pregnant?
