9 weeks symptoms easing normal?

So starting exactly at 9 weeks my symptoms are easing. I was so nauseated weeks 6-8, that when I was hungry on my first day of week 9 I was shocked. Still can’t eat too much, but I do actively go to the kitchen to snack now. I have slept through the night (without having to get up to pee) two nights in a row now. So I am wondering if the better sleep is making me feel better in general...?

At first I was nervous thinking I feel better, am I still pregnant? Like should I contact my doctor, since it has been a week since my last healthy ultra sound. Is it time to freak out? But my hormones have kicked into high gear in terms of being emotional. More so frustrated with my husband like I am pmsing x 10.

Has this happened to anyone else?
