Just read through this whole thread. I'll consider placing my vote with the not pregnant side. But only because I've had a couple of those same symptoms and I can guarantee there's no pregnancy here.

On the pigging out - no pigging out more than normal here, but I do love to snack a lot (and no "growing teen" excuse at 24) - especially on salty or carb-heavy things. (And now you've got me craving Wendy's!)

Short periods don't mean pregnancy. The past 2 months I've had 3 day periods (no complaints there!) that looked normal enough with a killer migraine on the day before it ends. Heh! If anyone tries to say pregnancy here, it would be a virgin birth.

And any nausea... Well, around here the flu is running rampant. So that might be another possible explanation.
