Cramp and brothers

So, I live with my brother he is younger than me. And mostly I never get cramps but when I do it hits me real hard, I won’t get out of bed and I won’t be doing most of the things I do on a regular basis. But this time, like I just couldn’t get up to do the dishes and now I’m the bitchy monster that never cares about anything, I just don’t get it, why do guys almost never understand that we bleed monthly and that it hurts??

I’m just being emotional and needed to just get that out, thanks
