Girl on period

As a girl, I can say this is an accurate representation.

Isn't it supposed to be more violent than this

Then I must be an alien, because this isn't how my period works..xD

Could someone chime in on this and help me out? I can't help but get the feeling that this might be a repost... the reposting part doesn't matter, it the trying to remember that's driving me a bit batty.

It's almost like we see this once a month, right about the same time.

As a guy i can say yes to this as my girl usualy cuts me and leaves me crying like that in a puddle of my own blood whe ahe is on her period
