Am I starving myself or becoming Anorexic? or even Period Pains?

Lately ive been sleeping during day awake 2 night and i was asleep and i woke up from a stomachache. I thought i was hungry but i ate the ceasar salad my dad brought me from work and it still hurted. So i thought i had to go to and i did when i noticed i was on my period. Then i went to my room turned the fan on but it was too cold but felt good BUT it made my stomach hurt. Now I'm not eating anymore. Not that i don't want any but i'm full. I just ate the chicken breast and some greens. I still see my plate half full i only ate like 5-4 chicken breasts.. anyways which one is it from above? Please answer Best answer 10 points :)
