I took Plan B on October 22nd (two days after having unprotected sex, but there was no ejaculation). I got my period a couple hours after taking the pill, which surprised me because I wasn't expecting to get it for another 2-4 days. My period lasted for nine days.

It is now November 22nd. I do not know if Plan B restarted my cycle or something like that? If so, I would be about 3-5 days late at the moment. Would my period be delayed because of Plan B? I've read no information about it making your period come the same day as taking it, so I have no idea how the whole cycle thing would work here. Help?
