Can not complete the 1st Trimester Screen???

Malori
Hey all. I had had three attempts now to get a visual and measurements of my peanuts neck to complete the 1st trimester screen and they absolutely can not get it because my baby will not move and he/she is sitting straight up and down facing my belly button with his head down. I went this morning for last attempt and they said they "kinda" got a measurement and it looks ok. I'm still not happy with this and feel like a "kinda" measurement won't give as accurate results as possible and they are just guessing at this point rather than just moving on to the DNA test. Anyone else experience this?
