What do it mean when im always hungrey while im on my period now. i have never experienced this before?

Progesterone: Just before your period and during your period your levels of progesterone are higher and progesterone, one of the hormones produced in the ovary, is an appetite stimulant, so very very normal to feel hungrier around the time of your menstrual cycle. I try to remember that and not try to overeat.... it's just the hormones talking!!! :-)
