April 1st I had taken the Plan B pill (6 hours after the "incident") and on April 7th I started to lightly bleed, which got heavier like a normal period (a couple clots, TMI sorry) for 2 days and then went back to very light. So I'm total I've be n bleeding for 5 days. I am not due for my period until the 15-18th (irregular cycles). Could this be my period that just came early or would this be considered withdrawal bleeding? Also, if the amount I bled was more than just "spotting" for even a couple of days, would this mean that the ECP worked and I am not pregnant?
