I took Plan B because I'm a hypochondriac and my boyfriends tip went in slightly and may have had precum. So anyway, this happened about 6/7 days before my ovulation date, and about 2-3 days after my period ended.. I took the pill 12 hours later. A week later I started bleeding and still am kind of, at first it was light pink spotting that turned into a decent flow of bright red, now still bright red but not as much. It's been 4 days, I've heard it's either withdrawal or really early period but I don't know how to tell. My boobs just started to get slightly sore but not too much. My actual period isn't due until Christmas the 25th of December. Will it be late? Can I be pregnant?
