Chocolate issues??

Ever since I’ve had my period as a kid, I’ve never wanted to eat chocolate or sweets. As a current teen, 16 going on 17, every time I’m offered chocolate during my period I feel just a huge urge to throw up. I eat other fatty foods after and before my period, but it’s only during my cycle where I only want to indulge on bread or a grilled cheese sandwich.

Is there something wrong with me for not liking chocolate or fatty foods during my period?
