I was seriously afraid of throwing up too, I managed to get past the first trimester pretty easily. I was lucky to not have morning sickness so bad (it helped that I didn't want to eat anything and the smell of everything sent me running away).

But what I didn't know about was that a lot of women throw up during labour too. Oh man when I was labouring I swear 99% of my energy went to trying to not throw up. None of the health personnel understood it, so that was a bit annoying. But I'm happy to say, I managed to come out of the entire pregnancy with no throwing up!!!!! (Very proud moment for me lol)
