Should I worry of not knowing HCG levels since doctor won't see me till 8 weeks

I went to fill out papers at an Ob/Gyn when I first found out I was pregnant in week 4. They did not take any blood work and said they wouldn't see me until 8 weeks. It's my first pregnancy so I've never been considered high risk so is that why she doesn't want to take my blood work because she doesn't think I'm high risk? I will be 6 weeks this Saturday so I just worry because everyone is talking about how they know what their levels are and I haven't had morning sickness so I'm freaking myself out that maybe I shouldn't wait till week 8. I haven't had any bleeding either. I think ill just take another pregnancy test in the morning before work to feel "pregnant" again. 😭 only symptoms are not being able to sleep, peeing a lot, and cramping from time to time.
