pregnancy symptoms calming down?

Erin
I felt so sick for awhile and had consistent cramps and tummy issues, but a few days ago things started calming down. I'm still having nausea, I'm tired, my breast are sore and sometimes smells make me gag but no  real cramps and no vomiting. I'm 7 weeks 3 days now and wondering if other people feel a calming down of their symptoms around now? I have my first ultrasound this week and I have worries since my symptoms have calmed down. Let me know if this happened during your pregnancy?
