🌈 baby and anxiety

I had a mc in April and just found out I’m pregnant with our 🌈 baby. My doctor won’t schedule an appointment or an ultrasound till around 8-10weeks. As a compromise he scheduled blood work 96hrs apart to look at levels. First one was around 2000, second was around 12000. The nurse called today and said the dr is please with my numbers but wanted to remind me that doesn’t mean it’s a viable pregnancy. She also said he might not schedule an ultrasound till 18-20 weeks. I’M FREAKING OUT! He’s a good doctor. There’s just so much anxiety inside me. I really want to call and see if he’ll order bloodwork every 96 hrs till my appointment (which would only be 3 more times) just to monitor my levels. Anyone dealt with something like this? What’d you do?
