Morning after pill

Emma
Hey can anyone help me?, I took the morning after pill about a month ago, a week later I started bleeding really really light, literally when I wiped down there, I kept bleeding like this on and off for two weeks, I'm 12 days late on my period.... Could it have been the morning after pill bringing my period on before it was due?, a couple of my friends have said it sounds like an implantation bleed, that was the first time id ever taken the morning after pill please help
