Couple random pregnancy questions?

Hey lady!! I was able to find out I was having a boy at 16 weeks and two days. We called him DarthDarth binx because that is what are son was calling him. I don't know why he calls him that but it stuck. Are they going to do a sonogram at 14 weeks? I am high risk so they do a sonogram each time I go in but if you are not high risk they may not give you one until 16 or 20 weeks. You would be really lucky to find out at 14 weeks but that can be too soon to call it for sure.
