i have some scans from 13 weeks and just wanted opinions on gender. one shot the head looks very round. the second one you can see there is a very straight line but theres also a bunch of fork looking endings on the far right of the baby. looking at the babies position in it makes me think the straight line is the other leg bone?. 3rd picture theres a second shot of a possible nub aswell but its lower so im not sure which picture im susposed to go off
