Oh shoot
That happened to me during my last pregnancy, for my anotomy
Scan... I had to go in again and after a couple of days and it still wasn't a good position, so they made me drink cold water n walk around n wait an hour,
They were finally able to get the Measurements. I asked the tech about the gender and she said she can't really tell cus of the position,
I told her to pls guess and she said well its 50/50 but leaning towards a girl
And when I have birth I had a beautiful baby girl!
I'm not sure what else would help, besides juice... maybe a little pop?
Or cold water.... also walking around cus that's what they made me do...
I guess they'll keep trying so they can atleast get the measurement..
I've also heard girls cross their legs more than boys do, and a lot of times in a case like this, it turns out to be a girl, but I'm sure there's still chances of it being a boy as well!
Good luck tomorrow !
