Symptoms going away

Cheryl
Has anyone experienced a major decrease in symptoms as early as 9 weeks? I was moderately nauseous all day every day from about 5 1/2 weeks until just a couple days ago. I still get a bit nauseous if I haven't eaten for a while but nothing compared to what it was. I'm grateful for the respite but kind of worried. I had a miscarriage last July and the first thing I noticed was my symptoms decreasing around 10 weeks. 
Has anyone experienced lack of symptoms this early and had a healthy pregnancy?
