So I am 22 years old and a few weeks ago I took the morning after pill (plan b). Everything seemed fine, but a few days later I experienced some brownish/red bleeding which I assumed was my period. (Could have been spotting). It stopped for a few days and then came back with a vengeance, and I started to have really HEAVY BRIGHT RED menstruation like I have never experienced. I am pretty small and the amount of blood is definitely not like what I normally experience on a period. Is this okay? Its now day 4 of really bright red and heavy bleeding and I'm getting scared. :'( What should I be doing??
