Stressing over hcg level

Alissa • Dear son born 5/7/18. Three angel babies. Dear son born 8/27/20 and pregnant with our first girl and last baby Pittsburgh PA-C

Currently 4w pregnant.

Had a miscarriage at 7 weeks in March. During that pregnancy, hcg was 152 at 4 weeks and when I ultimately miscarried at 7 weeks it was 2057.

Now my hcg is only 62 at 4 weeks 1 day.

Any one else with lower hcg that kept their pregnancy?

I will go for repeat draw on Sunday but I'm trying not to get too worried about one number...
