Okay well I Started my period on July 24 and ended around the 28-29. I had sex on July 30. I took a plan b pill the same day because the condom broke but he didn't ejaculate. It's exactly 1 week later and I bled some today, but it looked sort of brown. I took a pregnant test and it came back negative. I'm not supposed to ovulate until August 9th. I've been having headaches and back pains (period pains they feel like) & kind of feeling sick because of my headache. Is it from the plan b pill? & is it normal to bleed or "spot" a week after you take the plan b pill?
