Suddenly aunt flow wants to be on her own schedule

I got my period yesterday. 28 freakin days before my wedding. My gyn can't see me till tomorrow afternoon I dont even know if i can take the time off.
I've been off the pill so long I don't even remember how it works. Grrr!

It's probably stress related. I got mine on the HM. Sometimes things just $uck like that. Sorry!!
