yes, India made legal gender change impossible but my friends have always gendered me correctly and stick to it even when it confuses other people and my friend's little sibling calls me older brother in Kannada yes, India made legal gender change impossible but my dog learned my new name quicker than the humans and she runs to give me a kiss when she's told to without being confused about who's being referred to

yes, India made legal gender change impossible but I can feel the Adam's apple growing in my throat and my muscles getting stronger, and my smile more real and I'm growing a beard, and I talk more freely

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.
