9 Weeks 4 Days and don’t feel pregnant

I was so nauseous and so sick just last week. But over the past couple of days I haven’t felt pregnant at all. Mildly sore breasts and some small cramps. I had an ultrasound 2 days ago that showed a very active baby with a heart rate of 176. I also didn’t feel very sick then either. Anyone else’s symptoms just suddenly stop and everything been okay?
