Can two pregnancys really be that different?

Caitlin

Are there any mum's out there who have had hyperemesis with one pregnancy and not the other ? With my daughter who's now 6 I was soooo sick with her, ended up in hospital it was awful!

With my second pregnancy I was sick but not like with her. That ended at 13 weeks last October :(

Now I am nearly 8 weeks with pregnancy number 3 and although I am nauseated it's mainly when I haven't eaten. And only dry gagging some days.

I guess what I am asking is .... Can two pregnancies be that different?
