Anxious

I am 4 weeks 4 days today! I called my doctors office yesterday and because I have no history of termination, miscarriage, no medical issues with my last pregnancy, and I know my LMP, I am not having any blood work taken and no appointment (7 week phone intake with a nurse) until my 12 week ultrasound/doctors visit. Am I stressing myself out feeling like I should have blood work to make sure everything is okay? I have been getting positive tests since 10dpo. I just need some reassurance that this is normal and that everything will be okay. I’m sorry for being so anxious.
