I've been on BC for about 2 years now. I'm never late or have never missed a pill, so is the case this month as well. I'm concerned however, because I'm almost a week early. I have 4 active pills left to take, and my withdraw bleed usually doesn't start until my 2nd/3rd inactive pill. Husband and I had sex last night, woke up this morning with some red blood, dark red, still bleeding, slightly crampy as well. Have been under stress this month as I did start a new job. Could this be a factor as to why it's early? Could it be something else? As I said, no missed pills and always taken on time, with maybe a 10 min. difference give or take, but most of the time at exactly 8PM when the cell alarm goes off. Is an early period here or there something that can happen?
