I took Plan B about three weeks ago, and went and got a pap test and started on the pill 9 days ago. I started spotting on the Saturday then started the pill that Sunday but my flow stopped and started up normal on that Wednesday. (Expected start date.) It is now Thursday. and I have had my period for either 8 (normal day) or 14 (day I spotted). My period isn't heavy, just lasting for a long time. Does this make sense with Plan B? Thanks for the help.
