Dizziness and Headaches at 14weeks 6days.

queenie
I'm 14weeks 6days today, I've been feeling light headed every once in a while. It's like everytime I need to eat or drink water. Not that I'm starving or really dehydrated. I was cooking yesterday and while waiting it started, i had to rush to get something to drink, i fell and had to lay down for a while for it to pass, when it happens there's nothing I can do than to just lay down helpless, I think it's the baby saying "NOW!!" Nauseousness has also gone down a lil bit but cant keep food down sometimes, and i get migraines after throwing up. Is it normal? Does any1 feel the same?
