Symptoms went completely away?

I am now 9 weeks and have no pregnancy symptoms. My boobs were really sore before I even found out and I had pretty rough nausea from 5.5 weeks to 7.5 weeks. Now I only get nauseas when I go too long without eating, which was similar to before I was pregnant. My breast soreness went completely away. I’m on progesterone, so it makes me nervous that my pregnancy has stopped progressing and the progesterone is just keeping me pregnant. Anyone else lose their symptoms early and go on to have a healthy baby?
