Blood work or wait until US

Br

So this is my second baby, but my first pregnancy experience was so different that I’m not sure what to expect from this pregnancy.

My doctor wants to see me at 8 weeks for my first ultrasound, and that is the first I’ll see the doctor for this pregnancy. Should I be getting blood work between then? I had my first ultrasound at 5 weeks with my daughter. Is this normal?
