I've been wondering about my period. I've been really hungry lately, and I googled on the internet that when before and after your period, you crave a lot of food. Also I weight myself every day, and I gained abour 3 pounds overnight. I thought it was impossible, but then I realize it was my period.. If I eat a lot, because of my cravings. Well I gain more weight, or just take off the weight that I've gained over my pms.
