I am throwing up everything I'm taking in. Even water! Any help to solving this will be great. I've also lost 5 kg in my first trimester.

It is common to lose weight in the first trimester. I didn't feel like eating anything either. Chicken soup or porridge would be great. Any sort of comfort food which is easy to swallow and nutritious. http://www.pregnancycorner.com/pregnant/pregnancy-symptoms/weight-loss.html
