Why are most women always really b*tchy when they have their period?

PMS=Putting up with Men's S***!

bitchyness is apart of someone's personality but yes, periods cause a dramatic change in a woman's hormone levels similar to pregnancy. some have it worse than others. but don't let a woman use "pms" as a reason to just be a grouch. it is not a crutch and even if a woman snaps on accident and has an attitude, she shouldn't be too big to not apologize for it

are you a guy? if you are a guy you will never understand the hell we go through on our periods.cramps,bloating,very emotional,and we still have to deal with everything else and dont even get a break.it dont help when guys are being annoying about us being bitchy either.

something to do with hormones but im not entirely sure which ones. I'll fess up I can get kinda bitchy :) I dont mean to be though haha

i wouldnt call it bitchy, buts its disturbed. i have had my period for almost a month already and it annoys me going to the restroom during school hours.

It's not just my period; I'm a FIERCE BETCH allllll the time.

How about u bleed for a week straight, with cramps, bloating, people calling U bitchy, and guys being ignorant about what women have to go through?? I would love to see guys go through wat women do. HA, they would break

because of the increased number of hormones in their bodies. also sometimes, the cramps can wind people up. they do for me.

depends on who your with. aand whore moans.
