That two pregnancies could be sooooooooooooo different!

With Annabelle I had sore boobs and NO sickness! I could stand all smells etc I was exactly the same as I am while not pg.
Yet with this one, I get sick at nearly EVERY food smell, I get soooo hungry then eat a TINY bit of dry toast and Im full, only to be hungry again 1 hr later

Im TOTALLY different! Im just hoping the birth isn't to different!
