How many of you become cranky emotional wrecks on your period?

I am trying to prove a point to my boyfriend that it’s very normal for women to become very emotional and easily agitated when on their period. I am not doing this in the effort of making an excuse for something crazy or mean I may have done to my man but he really doesn’t believe me. According to him, none of his friends say their girlfriend gets super emotional or snappy and therefore I am wrong (even though I am a woman but apparently I wouldn’t know how a lot of women act I their period). I personally cry a lot during the seven days of my period. His includes crying during sad movies or crying during small arguments as I rant about dishes not being done and such. Then period ends and I’m back to my normal bubbly self. Anyway, I cannot be the only woman that goes through this!
