I dont know what to do. My last period was on September 20th, I had missed 5 birthcontrol pills that month. My period was light for that weekend. ended saturday, early sunday. I had sex that monday, then again that friday. I should of ovulated like Octorber 1st. Went take blood work and came back negative that I wasnt pregnant. Since I started taking my birthcontrol for the month of october, i have been spotting this brown stuff with cramping, and it has yet not went away, my period is expected next week. Can i still be pregnant, and they just couldnt determine it that early. Or can my birthcontrol be working if i have been spotting and cramping almost the whole month of this month while taking the pill. What to do?
