Hi, trying to figure out the nub theory and wondering if anyone could help guess? The twin scans are at 13 weeks and 2 days. The first three are twin 1. Thanks x

The twin 2 scan is not great but attached anyway here.

Ooh, I'm guessing a girl for twin one. I don't understand the nub theory so that's based on the skull theory, but my accuracy rate is probably only about 50% wink. Can't really see well on the pic for twin two. Are they identical?

Ooo thanks, that sounds interesting - I've never heard of that. They're not identical but twin 2's scan is really hard to see!

I'm sure it was on MN that I read about it, but as I said I'm really not sure it's very accurate! If they're non identical I will guess one of each (unless you are one of many sisters in your family, in which case I would guess 2 girls as anecdotally among my friends that seems to be a 'thing'!) grin
