Tips for keeping up diet while on period?

I have the world's most awful periods (hurts to move at all, always hungry, cravings through the roof, extremely emotional) and this is my first time on my period since I started a 1200 calorie diet last month. So far I've lost about 7lbs and I don't want to lose all that work because of my period.

Any tips on how to keep up my diet through such a turbulent time? Or any foods you use to quell your cravings during your periods? I just know working out won't be an option since walking to my kitchen to eat is enough to make me cry from pain.
