Yeah it's normal. Be lucky that you haven't got it yet :)
On my 3rd pregnancy never had sickness or nauseous through out the whole pregnancy on all 3 babies feeling blessed. Just one of the lucky ones. Some of my friends suffered a lot. Just enjoy.
I'm on baby number 3 and I get sick as a dog from conception, have been feeling fine so far (7 weeks) consider yourself one of the lucky ones :) would not wish nausea or morning sickness (24/7 sickness) on my worst enemy, it's absolutely horrible.
I started getting nauseous around my 8th week and I find it hard to get out of bed because im so queasy.
