20 wk ultrasound

so yesterday i was able to find out that im having a girl!! lol quick question are those her little legs or her arms that you see there? its her legs right, probably she was just really curled up. Also, everything is perfectly okay with her im just concerned with 2 things. 1) they told me that she weighs a little bit more than shes supposed to. and 2) she didnt let the tech see her spine so i have to go back in 1 month to see if she lets them see it because she was moving way too much
