Boy or girl ??? Confused by picture!!!

Brianna
I'm 12.3 weeks and I read how people can tell the sex of their little one by that time if they are lucky. What is everyone else thinking. This picture makes me question whether it's a boy or girl. It looks like a boy but then when you look closer there is a nub that goes straight! Help I would like some input on what you guys had and if it's similar to mine and what outcome it was/is:) thanks!!!
