Ive been on microgestin for almost a year now, and never missed a day. The second week on my pack I took my birth control late, and then the week before I was supposed to get my period I took two in one day, and had unprotected sex after I took the two pills. I saw one day that there was a little blood when I wiped. But other than that I haven't had any other signs of my period except an occasional cramp or two. I started my new pack today. Could I be pregnant?
