Nervous for first appointment!

Kendal
Hi ladies! I'm 7 weeks+ and I'll be 8 weeks Monday when I go in for my first appointment. I went in a few weeks ago for a pregnancy confirmation, basically just a urine test to say yep you're pregnant. I'm nervous for my appointment. I don't feel pregnant- haven't had any bad symptoms like morning sickness. Mainly it's just been weird dreams, cramping , tired and hungry. I'm scared I'm going to go to m appointment and they will tell me I'm not pregnant anymore or my levels aren't rising like they should be. I haven't had any spotting or anything, I guess it just doesn't seem real. Has anyone else felt like this and have you felt better after hearing the heartbeat? I'm trying to be cautious and not get too attached to the idea in case I do have a miscarriage. I really hope it goes well because we are planning tell our family at Christmas next week!
