HCG levels

Hi all. I’m 6 weeks 4 days and had a missed miscarriage in June. I’m definitely anxious this time around so my Dr agreed to test my HCG. It was 60,000 on Wed and 78,000 on Friday but apparently the Dr said that she would have liked to see it increase more?? I read that once your HCG is that high then it might not double in 48 hrs. Anyway, it wasn’t as reassuring as I thought the test would be so I’m feeling like it was useless to even get my blood drawn... any reassurance welcome.

UPDATE: they got me in for an ultrasound today and everything looks great with baby measuring 4 days ahead of LMP! 🤗😁🙌🏻
