I'm having a girl but everyone tells me I carry like I'm having a boy

I don't know why it bothers me, but I have had Blood tests and multiple sonograms confirming I'm having a baby girl. So many people tell me I look like I'm having a boy because I'm all belly and I guess not gaining weight anywhere else. It's annoying me a little because who can really tell how you carry as an indication of what I'm having even after confirmation from doctors and labs. I guess it makes me nervous because all everything I got is for a girl. Just venting!
