Did anyone's bloating go away?

Ira
Hello ladies....I am 13 weeks and 5 days pregnant  and have been terribly bloated for the last 3-4 weeks. However since yesterday my bloat has gone away and I don't "feel" pregnant anymore (sore boobs gone pretty much too). My stomach is noticeably smaller. I had my first trimester screening ultrasound 10 days ago and that was normal, I have not had any bleeding. Should I be worried?
