haven't eaten since Saturday!

I literally haven't eaten since Saturday! ( I live on ginger ale) I  found out 2 weeks ago that I'm pregnant, I could be 8wks or 5 wks, still waiting on first ultrasound to tell. I have no appetite whatsoever! I eat every 24-48hrs and the only thing that bothers me is the gas and bad feelings that comes with being hungry. Is all this part of the baby making process? Someone please tell me they've been through this before and survived.. 😕😫😩
