Nope. How you carry is nothing more than an old wives tale and is not accurate in any way as to the gender of the child.
some say its a girl and their guesses are good but i think even a boy can be carried high.
I am carrying lower and am having a girl. Plus with my first pregnancy I was carrying higher and it was a girl also. It really is wives tales, plus you have a 50% chance of girl or boy so sometimes they match up but more by luck.
My oldest son was high and youngest was low. I wouldn't go by how you're carrying. Some women also say you can tell by hb. High hb is a girl and low is a boy. This is also not accurate. Even ultrasounds can be wrong but this is more rare.
