My son was the same measured 33 weeks up to 37 weeks he was transverse laying then he moves at 39 weeks to head down and my belly popped :)

I measured 5cm under and turned out it was just the way she was laying as yesterday she measured normal xx

thank you x fingers crossed it's just funny position @winterbaby95

Could just be the position the baby is laying in hun :) I'm sure everything will be fine on the scan xD I was measuring 2-3 weeks ahead all the time and my growth scan came back all normal xx
