i keep seeing posts to the effect of "period blood isn't special or different than other blood" and in spirit that's true but i keep on having the autistic objection of "wait, I went through sex ed, it's not actually the same thing as blood, it's a mix of blood, enometrial tissue, and discharge/mucus"
periods happen because of the uterus developing and shedding endometrial lining on a roughly 28-day cycle. this is related to pregnancy but like everything about the reproductive system it is not solely related to pregnancy. the goal if you're avoiding menstruation is for it to fail gracefully - i.e. no endometrial tissue develops, no period happens. (this is actually perfectly achievable for people not on testosterone, most doctors are just weird about it and insist on birth control cycling because they have weird ideas about women.) the danger whenever it stops (which can be caused by dietary irregularity, hormonal changes, etc) is that it hasn't failed gracefully and endometrial tissue is still developing in the uterus, because if it gets stuck in there or escapes containment it can cause endometriosis, which is very dangerous. get that shit checked out if you're experiencing weird pain or irregular periods you can't explain some other way; endometriosis is detectable by a non-invasive ultrasound so looking for it isn't even all that shitty
above all i think mystifying the bodily functions of roughly a third of the entire human population is a serious mistake, and one that laypeople aren't alone in making (again, many doctors have extremely weird ideas about periods!). read up, stay on top of stuff, everyone's got a body and you gotta be good to yours. be ready to advocate for yourself in the face of being blown off by doctors too, they're routinely very ignorant and stubborn about taking uterine conditions seriously, especially if you're visibly queer/trans/nonbinary
to the terfs in the notes losing their shit bc OP said one-third not one-half: one of the problems with equating "capable of menstruation" and "female" is that means people who are pre-menarche, post-menopause, or post-evicting-cancerous-uterus cannot be female, even though most such people understand themselves to be female
