Rainbow baby after 2 mc, 13+1

[DreeaLondon]

Hello
Had 2 back to back MC last year and finally rainbow baby. I posted this in another group and everyone was pretty much stumped into what they saw, or some said the nub wasn't even pictures. It says 12+3 but measuring 13+1

Thank you

Yep what is captured there is mostly cord and the nub is not fully captured here. I need the full nub to be able to guess accurately. Any other shots?
