Slow rising HCG

Does anyone have any thoughts?

I’ve been bleeding and spotting since I found out I was pregnant about 2 weeks ago.

I’ll be 6 + 1 today. Last week a tiny gestational sac measuring 2.9mm was found on an ultrasound (I was 5 + 1 at the time). No evidence of ectopic pregnancy was found at the time.

The bleeding and spotting is a big concern, but most concerning are my HCG levels which are rising extremely slowly :(

(see below).

I’m having another ultrasound next week to further rule out ectopic/determine viability.

Likely miscarriage?? This is our first pregnancy 🥺

Beta HCG:

19th Aug: 170

20th Aug: 270

22nd Aug: 590

27th Aug: 1,600

28th Aug: 1,900

29th Aug: 2,100

A lot of tests I know, but I’m being very closely monitored.

TIA!
