I had an accident on the 10th and got plan b the next day. After a week of taking it i started to bleed like a normal period . But it only lasted for 4 days. I don't understand if that counts as my period. But today was the day I was supposed to be due and I don't have my period. Was the four day bleedING considered my period? (If so then is it normal to get a period 2 weeks early after taking plan b?)
