Maybe pregnant?

I shouldn't be, because we've been doing excellently with NFP, but we are happy with if we were to have an unintentional pregnancy.  I have been having weird pulling feelings in my uterus and I've been feeling a little nauseous in the afternoons (my mother always got night sickness) and (tmi?) backed up and AF is due tomorrow, but I'm not having any of my pre-period symptoms. Wish me some baby dust? Fingers crossed and baby dust to all of you out there)
