Twin nub/skull theory

[usplustwo]

Hi all. I'm having didi twins - pics attached are from our most recent scan which was at 13 weeks. I have tried looking at nub and skull theories but to be honest, can't even work out if there are nubs on the scan images! What do people think? After TTC/IVF for 6 years, we really don't mind either way, I'm just curious. We will find out in a couple of weeks but would love to hear any guesses x

No idea but congratulations on your pregnancy

Thank you :)

I’d say first photo is a boy and second a girl? Zero training and just what I’ve picked up so could be totally wrong!

Thank you - that was what I thought too, but I don't really know why as don't know what I'm looking at! X

Def 1 of each imo!!. Congratulations!!

Either one of each or two boys? I would say the first is a boy but I’m not sure about the second.

I go off the skull which is not as accurate apparently. The first looks like my ds. So tall forehead and it’s bigger at the back too. Not sure about the second because the head is more curved and smaller at the back, but still a bit of a taller forehead. That’s why I said that above anyway. Who knows if it’s actually right.

My guess is twin 1 boy and twin 2 girl

A friend who used to be a sonographer said she thought two boys based off the images so you could definitely be right.

I don't think this photo is any clearer but have added just in case. (Twin 2 on top, twin 1 on bottom.)
So interesting to see all the different theories! X
