OK, my period skipped December, my last one was November 27th, I think, last week, I woke up to a migrane, now I get a really short headache off and on, I've had tender breasts, it was bad at first now its mostly after taking off my bra they hurt they dont hurt as much, no spotting though, but my stomach is uber uncomfortable when it's empty and anything I eat or drink helps it right away, so I'm not 100% sure if I'm pregnant and I was wondering what else it could be, like my period is a little irregular but it only skipped once before this and that was a long time ago and I wasn't sexually active then.
