Barely any pregnancy symptoms (Worried)

ErinBeans

I hope i don't sound like a freak but here it goes.

I went about 2 weeks ago to my first  appointment where I had an ultrasound. The tech saw a baby and a heartbeat and said my gestational age was 7 weeks 6 days. Since the day after the ultrasound I have had almost no pregnancy symptoms! I never get sick, my boobs are barely sore and I just don't "Feel pregnant". I have been freaking myself out ever since waiting for my next appointment which is this coming Monday. I am afraid of a missed miscarriage. I should be about 9 1/2 weeks now if you count from the last period.

Should I be worried? has anyone else with children or are pregnant now have few symptoms or none at all and everything is fine?
