HELP 12+2 weeks NT ultrasound

Ladies I am stressing out. Went in for my NT scan yesterday at 12+2 weeks and the lady who did my ultrasound said that the results weren't super super accurate because the baby didn't want to move onto his back; he kept on staying on his tummy.

The measurements varied between 2.6 mm and 3.0 mm.

She said the measurements of NT were a little over average but my blood work would be way more precise.

The baby measured at 13 weeks though. And I am 25 years old, maybe it's important to know.

She didn't seem too worried and said next ultrasound is at 20 weeks... but going with what little she said,

it's stressing me out and I have to wait two weeks before getting my results.

Attached is my ultrasound picture.

Please reassure me and tell me this ultrasound looks like a normal healthy baby 🙏

And can you predict gender? ♂️♀️
