Not feeling pregnant anymore?

I’m 9 weeks 2 days my last ultrasound was 7 weeks 5 days and everything was perfectly fine. But after that I started having less and less symptoms. The only thing that has been consistent is tender breasts. Other then that all of my symptoms have disappeared including frequent urination. I’ve been pretty light headed if I stand up to fast and nauseas if I go without eating for to long. Just wondering if this is pretty normal? I don’t remember my symptoms going away in my first pregnancy. I’m a little concerned 😟
