Yep thats morning sickness! and it can last the whole first trimester or even the whole pregnancy. They say i you eat as soon as you wake up you should feel fine unfortunately for me that doesnt work. I had it horribley with my DD but its not so bad this time around. I find if i sip on juice or cordial anything sweet im fine.

Brushing my teeth always set me off so i ended up resorting to mouth wash until i was over the worst of it.
