opinions?

I took a morning after pill on feb. 12th, my period came a week early. 
I had unprotected sex on mar. 4, my period was expected on the 10th, it usually comes on the 27th-29th but, since I took the morning after pill I assumed it would come early this month.. 
anyway, has this happened to anyone? I'm totally fine with having another baby but.. I don't know.. I guess I just wanted to talk about this with other women.
