First Appointment Question

This is going to sound silly but I don’t know how/when to go about a first appointment...this is obviously my first pregnancy. I’m 5 weeks along. No period (I’m very regular with my period normally) and multiple very positive pregnancy tests (dye stealers). So I’m pretty confident that I’m pregnant. Not to mention a few symptoms as well.

Do I need to make an appointment for just a blood test to confirm first?

Do I go directly to a obgyn for a first appointment?

Help me with the first step!
