menu design help

Hello!

I am using the momoyo theme and on my site, there is a “hamburger” menu that blocks a part of my main header on the left side. Is there anyone who has any way to move this menu so it isn’t blocking my main header anymore? I should mention, this happens when you view my site on a mobile device.

The blog I need help with is http://www.htxnutrition.com.

also, I am very novice to all this so if anyone can explain a possible solution by walking me through what to do I’d appreciate it.
