ultrasound scan

Hi guys! Anybody heard of the nub theory gender reveal? I had my first oscar scan today and i seem to see the nub. Can anybody guess what gender is it? (: is my first baby so i am excited for any! But just trying to guess

Hi I’m currently about 14 weeks pregnant. Usually my gynae will give me one photo each time we had a scan. Is it ok to request her to take better clearer pictures and give me more than 1? Will gynae usually do this kind of requests? Thanks
