Why am I nauseous now, of all times..?

Aprilbaby92

3 days until my due date, and now i'm feeling dizzy and nauseous as crap.
But why? could there be something triggering it?
or is this just a normal stage you go through right before Labor?

Advice would be wonderful, along with some natural remedies to rid the nauseousness

Side Note: Crackers & Gingerale didn't work for me.
