I took a plan B pill 12 hours after unprotected sex about a week before my period was due. I then got my period a few days earlier but it was still normal (5 days and regular flow).
Today, I found some very light spotting on my underwear. It looks like what would be the start/end of a period. Right now should be around my time of ovulation. Does the Plan B cause ovulation spotting? Or is it likely that I am pregnant?
