7 weeks and no symptoms!!

Lendy
I'm 7 weeks today and I don't really have any symptoms . Weeks 5-6 had sore boobs and gassy but other than those two I'm feeling pretty good . I had an ultrasound on Mon 6/8 and saw my tiny baby and heartbeat but I'm so worried when I go on the 23rd something will be terribly wrong because I don't really feel pregnant .
