Weight loss

So I just weighed myself for the first time since last week. I was 230 then and 222 now. Idk how I keep losing weight tho. I don't have morning sickness. More like morning naseua. I force myself to eat throughout the day. I drink broth. Idk what else to do.

Im 6 weeks today and my first OB appointment isn't until Feb. 16. Should I try to get in sooner?
