Nausea and don't want to eat.

Hello mummies! I'm 7 weeks pregnant with our first child and the nauseousness is kicking in day by day to the extend that i find it so so hard to eat even though my stomach is hungry and growling. Just the thought of food will makes me want to gag so badly. I suppressed most of the nauseousness because i'm afraid once i vomit, it will not stop. I only eat for the sake of our growing baby. Any advice? Thank you!
