HCG 5 weeks 2 days

Breanna

I had a miscarriage in April 2019 and I’m now currently pregnant with our rainbow baby 6 weeks and 2 days. I got my bloods taken last Monday and only just got the results today . They were at 860. I was 5 weeks and 2 days. The doctor said they were low but not abnormal and she didn’t order another blood test. I have an ultrasound next Monday and am just a bit worried now that they are low..... Please help 😰
