New pregnancy and worried about high HCG

I’m almost 5 weeks pregnant sub 2 TFMRs (T13 and T21) and my first home test (day after missed period) was dye stealer. I did bloodwork yesterday and HCG was 1511. I know a standalone test can’t tell you much, but I was 4 weeks 4 days at the time and the chart on the test shows a cutoff of 10-750 for 4 weeks and 217-7138 for 5 weeks.

And I know high HCG can be associated with trisomies. I’m just very anxious and so badly want this to be a healthy pregnancy and to be able to get to hold this baby at the end of it.

Anyone have any post TFMR high HCG success stories to help my nerves?
