10 weeks?!

I ended up deciding to switch from my family doctor to an OB with great ratings and recommendations, but they don’t do first appointments until 10 weeks. I’m 6w3d and I’m honestly devastated I have to wait two more weeks than I planned. I’m mostly scared of going and finding out the baby stopped growing early and I could’ve found out at normally at 8 weeks , you know? But I also want to stay with this OB because they seem amazing. Can someone just give me some peace of mind?
