Not Sick

Bye!! ?
Posted this in my twins group, but wanted your guys' opinions too: 
I'm 8 weeks 5 days and I'm not sick! My breasts aren't sore and tender anymore and my fleeting nausea is now completely gone, I'm not peeing frequently, my appetite is back...point being I just don't FEEL pregnant at all anymore! I'm very worried about my twins and I'm afraid they stopped growing. What do I do? My next appointment is on the 12th...should I call my doctor before then to make sure everything is ok? I don't want to hear they stopped growing 3 weeks from now and be heartbroken thinking I'm 11 weeks. I've already told some people which I'm starting to regret because I don't know if they're there anymore. Advice please!
