Late OB visit/blood work?

I am currently 5 weeks pregnant and called to make an OB appointment. They said they schedule them for between 7-9 weeks which wouldn't be until July. I asked about getting blood work done and they said I'd get that done at my first visit. I see most people going to get their hgc levels and progesterone tested...will my baby be okay without these tests?? I'm freaking out a little bit. Thanks!
