First Appointment. 10wks.

On the 25th I'll be going in for my first, official, baby appointment. I'm so nervous. Most days I don't feel pregnant. Zero nausea. Little to no cramping. Some days my nipples are sore, other days they aren't. The only real thing I've experienced is fatigue; lots of it. I'm scared that the ultrasound is going to reveal something is wrong. I'm 38, and this is my 2nd time being pregnant; I miscarried with my first pregnancy 2 years ago. I want this child more than anything. I'm trying not to stress out too much, but I can't help it. Does anyone else experience little to zero symptoms still, at 10wks?
