Disappearing symptoms

Bianca
Getting worried. I'm 5w 6d and have been a bit nauseous and gassy and aching until about 3 days ago and now I feel great. No cramping or bleeding etc and no more nausea. I'm worried something is wrong. This is my third baby and I had terrible morning sickness with the other two from 5 weeks. Anyone else had disappearing symptoms and had a healthy pregnancy?
