oh? and men dont go through "mood swings" or their own versions of "periods" without ovulating, menstruating, bleeding/cramping/pissing and moaning, and so on and so forth? Riiiiiight... ive known many MEN to have a docile nature one minute... and an EXPLOSIVELY dangerous one the next based on situations they are put in... people they are conversing with.... and even just what kind of day, week, or month they have been having. PMS isnt real its just made up so the institutions can label us women as "insane and dangerous". The cramping and bleeding and pain and problems of a period CAN BE STRESSFUL and pit us in a mood yes... but we are NOT FUCKING PSYCHOTIC because of it. If someone is like that its usually cuz they are bipolar, manic depressive, or just batshit insane. There are plenty NORMAL CAPABLE women out there despite their periods that can handle it WITHOUT MOOD SWINGS.
In short... YOU FAIL understanding a woman and how she works biologically, mentally, and emotionally. You must be a misogynistic male to spout such bullshit.
