I don't know what I'm having

Am I the only one in this group that is having to wait until 20 weeks or so to find out what they're having? My SO thinks I'm having a boy, for literally no other reason than he said the legs in my last sonogram look like boy legs. I feel like I'm going to have a girl. I don't know how to describe or explain it, but it's just a gut feeling.
Anybody else have this feeling and you were right? Or am I crazy? I'm a FTM, first pregnancy. It's just a feeling, I don't know.
Let me know if you had this feeling and how it played out!
