Blood test?

I am 5 weeks 3 days today! Had my first appointment on Tuesday with the nurse practitioner. They did another urine test which came back + right away but they didn't take blood. Is that normal? I have a 9 week appointment with the actual dr on the 20th and they said they will do some then. Glow keeps telling me to confirm with a blood test.... So I'm confused if I should have had one already.
