Pregnant...no appetite

Hello moms!

My name is Nia and I'm 7 1/2 weeks pregnant. This is my first child so I have no idea what to expect other than what I read up on. But everyone knows when you're pregnant you start to eat for two. However, I'm finding myself eating less than I was before I was pregnant and I'm rarely Hungry. I have to force myself to eat and when I do I can't keep it down. Is this normal? I'm concerned about my baby's nutrient intake. Obviously he can't get any nutrients if I'm not eating. Plz help. Idk what to do. Idk if I should be concerned or not. My doctors appointment is a few weeks from now and I'm scared to wait that long for an answer. Any advice would be greatly appreciated.

Thanks in advance
