The answer is: the uterus isn't what causes your period, it is effected by your period. What causes your period and what causes trans women's periods is the same thing: the endocrine system.

HRT changes the sex of your endocrine system. Feminizing HRT makes it a female endocrine system, giving us a 28-day hormone cycle just like cis women. At the end of that cycle, the hypothalamus floods the body with prostaglandins. Those are what cause all but one of the period symptoms, because they make muscles inflame and contract. They are what make the uterus shed its lining, they are what cause intestinal cramps, they are what cause body aches, they are what cause headaches and migraines. The only period symptom not causes by the release of prostaglandins throughout the body is depression, and that is caused by your endocrine system simply not processing as much estrogen and from simply feeling like shit.

So, the only symptoms trans women don't get every 28 days is menstrual cramps, because yes we do not menstruate since we don't have uteruses. But migraines, depression, body aches, intestinal cramps, and the infamous "period shits" don't exactly add up to us having any better of a time. Except we have to pretend that we're fine and nothing is different because no one believes that we get periods, not even cis women.

Infants are given a vitamin k shot at birth because they cannot synthesize vitamin k or get it from their diets, it is vital in preventing vitamin deficient bleeding which can cause death or permanent brain damage. Administering the injection is a bog standard preventative measure done on newborns immediately after birth, usually automatically. More and more parents are denying it and more and more babies are having totally preventable complications in their first 6 months of life just because the vitamin k shot has a black box warning. Doctors are repeatedly trying to explain to parents that babies need vitamin k and parents just keep asking “Why? Why are babies born needing vitamin k? Humans survived for thousands of years before it was invented. This must be a conspiracy.”

Infants, the human life stage notorious for randomly dying with no easily discernible cause. I don’t say that to be flippant, human babies are so incredibly fragile that before the modern era, about half of them died before adulthood. That is a natural 50/50 of making it. Humans did not evolve to be perfectly designed and efficient, we are just functional enough for some of us to survive to adulthood and reproduce. We don’t have to live like that! Looking at the human body through the lens of infallible intelligent design and allowing that to inform your medical decisions is so fucking dangerous.

"Well if childbirth is so dangerous, how did humans survive so long?"

Because 1 in 100 is not an extinction-level rate of maternal mortality, next question.

"What do you think people did before Vitamin K shots if babies are so vulnerable?"

Infant mortality was 16.5% in 1900 and even higher before that, next question.

"Women have been giving birth for thousands of years, don't you think they know how to do it by now?"

Women have been dying in childbirth for thousands of years, next question.

the cambrian period is TOMORROW!!!
