12week ultrasound scan is it normal?

It is still too early to see your baby face shape. Your baby will still grow and change along the way. Also, it could be the camera angles that make some parts look different. Don’t overthink too much. If the gynae did not mentioned anything, it means your baby is all good. Trust your gynae.

if Dr didn't say anything it should be fine! my baby's face looked really flat so I was worried but I read online that baby's position can affect how the ultrasound looks like so it's not so accurate unless the sonographer really waits until baby is in a good position to take a picture.

you paid to see a gynae so just have trust in her/him instead of seeking non-professional advice here
