12 week vs 20 week scan

[2017Babyontheway]

Had my 20 week scan today and we didn't find out the sex however wonder if anyone can tell from my scan pictures at 12 and 20 weeks the sex!

I have no idea but what lovely scan photos!

Forgive me for being a donut but why didn't you find out?

Husband wants a surprise but id love to know!

I would guess a girl, they are lovely pictures OP

Girl. Your 20 week scan is so like my daughter's and I'm sure I can see the three lines for her life little lady parts!
Congratulations either way, they are lovely x

Skull theory on the 20weeks would indicate girl :) x

If it's a nub I can see on the 12 week scan I think possibly boy, possible stacking at the end, but I am not known for getting it right :)
