Losing too much weight while pregnant?

I’m 11 weeks today. I started out at 5’6 and 120lb at about 6 weeks I was at 125. At 10 weeks I dropped down to 117. 2 days later 115. Today I weighted myself at 110. I’m really concerned because I thought I was supposed to gain weight? And it looks like I am but the numbers are going down?? I’m just really confused, I haven’t been working out at all, been eating more. Idk am I ok or should I try to gain weight? On appointment not for a week and I’m stressing too much over this to wait ..
