Waiting for first appointment


I got my bfp yesterday. Called the doctor this morning to set up an appointment and they scheduled me for Dec 3rd. Glow thinks I'm 7 weeks. I think I ovulated late so I may only be around 5. It's it normal to have to wait so long? I guess that'll put me at 8-10 weeks depending on how far along I actually am. I'm just worried something will go wrong or I should be doing something different. Granted I have this app and you wonderful ladies for guidance. I'm still nervous.
