Weird Beta HCG numbers

Jenna

Hi ladies. I am asking for your thoughts on my betas? This was our 3rd embryo transfer, transferred 2 embryos on Jan 10

First beta 12dp5dt: 388

14dp5dt: 430

17dp5dt: 1283

It’s still not super high but I thought we were miscarrying after our 2nd beta. Has anyone seen anything similar?
