TMNT 2012 with an AFAB s/o on their period
Note(s): I wrote this with a ftm Reader in mind, but there are no gendered pronouns or gendered titles used.
Characters included: Leonardo, Raphael, Donatello, Michealangelo, April O'Neil, Casey Jones.

Leonardo
Listen, as much of a leader and confident guy you may believe he is, he is still a mutant turtle who does not get periods and only knows because it was mentioned in a show once and he wanted to know more. He will not understand, beside the basics of 'bleeding down there, intense hormones, and sometimes unbearable pain depending on who you ask.'
If you're someone who goes through a lot of physical pain expect an overbearing mother figure now in your life, he will literally be there with all the advice he can find that'll help.
With the limited resources in the lair and the fact he can't exactly go shopping himself, he'll ask April or Casey to buy period products or pain relief tablets for you if you complain. Even if he's awkward and shy about asking, he doesn't want to burden you by making you wait for a reply over text or have to get up, the fact it helps you makes it worth it.
Soup is also good, he knows how to make traditional teas and soups for you, with great difficulty, and help from Splinter, that will lessen your stomach cramps. Though if you get cravings he may be a little less helpful, it's hard to get ingredients when you live in the sewers and are hated by most of the world.
If you like company he would stay off patrols once or twice, but he's fairly strict about his schedule and won't go too far off it, even if he wants to help you.
If you don't get much pain, he's still by you in his free time and asking questions, you're literally bleeding he's never going to stop worrying.
Whenever you talk to him he basically soaks in the words like a sponge and uses it to help you, a one off 'yeah, this food helps.' and he's on his knees begging for April to buy some.

Raphael
Raphael... I love him, but he needs help when it comes to this. I imagine most of the other turtles at least know the basics, Michaelangelo is the worst but he still knows what a period is, but Raph just never really cared enough to learn.
He knows that a period happens... But that's about it. So, if you're in intense or even a small amount of pain and or wake up with blood around you, he's freaking the hell out, he thinks you've been stabbed or something or maybe he accidentally hurt you with his sais as you slept.
If you explain he's sort of like 'yeah whatever, how do we stop it from hurting you?' and then he never leaves your side.
You run out of products? Step out the way Casey and April, he's sneaking in the shop and thieving- I mean, he's putting on a trenchcoat and hat to hide his turtleness, and buying the products like a good mutant ninja turtle should. But seriously, he doesn't trust the two to buy the right ones, he gets the exact brand right somehow, even if you never tell him what one you want.
He pushes the exercise side of it, even if it doesn't help much, exercise is something that helps him so when he hears it can help he doesn't research further. It takes you explaining that it not only depends on the person but the exercise for him to pout and let you lead.

Donatello
He'd probably panic for a while but then tries to look through a science lense, like, oh! You need to level your blood sugars in this week, these excersises will help you but these won't, make sure to keep your stomach warm so you can lessen the contractions and pain.
Gets a bit sad if you're the type to be more distant and want alone time on your period, especially if you don't like loud noises. Donatello usually has you watching him while he works on his science stuff, so when you aren't it's a demotivator.
Ends up completely abandoning his work just to follow you around like a sad puppy, tending to your every need or waiting outside your room for a text from you if you need something.
If you want him around he's a lot more easy going, if you don't mind sitting in the lab with him while he works then he's all for it, of course he's checking on you every once and a while, and will talk when he wants to, but it comes from him wanting to help you.
If you have health issues caused by your period or your period is made worse by your health issues he's helping you a lot, he knows a lot about human anatomy and how to help ease pain, especially since April and Casey started hanging out with the Turtles more often.
He has a whole section of a diary dedicated to you, and that includes your period, when you're due, what food you've told him helps you, what foods you've said make it worse, what pain you usually describe as, etc, etc.

Michealangelo
Michaelangelo is 100% the type of guy who just goes along with what you want because he wants to help, he probably knows that you bleed, you get mood swings, and you're in pain. And that's all he needs to know.
He's watching you for your entire cycle and just PRAYING nothing bad will happen, gives you all the food you want, no matter how unusual. This can sometimes make it worse, because cravings aren't always foods that will help you, and he feels really really bad if that happens.
He tries to hold himself back on just giving you whatever you want, but when you look up he just folds and starts treating you like royalty.
He can't make a lot of normal foods, he can make pizzas and maybe a decent sandwich, but besides that he's a bit useless, so he tends to buy you microwaved dinners. Unless you don't like them. And then he's just lost.
Mikey asks Donatello to help on the more science level, like no, chocolate will not help, that's a dumb myth, it will only make your sugar levels higher and increase pain, plus blood flow, and nobody wants that.
Cue Mikey closing the oven to hide his chocolate pizza he was making for you.
When buying or storing products, he tends to sort of forget how expensive they are, he'll go in with only a couple of dollars and fall to the floor in utter shock upon realising that is not nearly enough.
But he may or may not steal a few, he saves the city, he gets no money from it, this is completely justified in my opinion.
It's not like he tells anybody anyway.

April O'Neil
She understands so much, whatever you need she'll get for you within minutes.
If your cycles match up April and you will have days where you just sit down and cuddle together, usually at her apartment or in the lair.
She's most likely the one who goes shopping for stuff since she's usually shopping for the turtles as well, though you can come along or even do it yourself if hers is painful and yours is bearable enough to go and vice versa.
If you don't get much pain or mood swings, she makes a few jokes on how she wishes she was you, but if you ask her to stop she will.
Understands the pain that might come mentally, if yours is really bad during the month she even ignores the Turtles to help you out. Unless you want to be left alone in which case she can do that as well, but she will text you every few hours, this is probably happening with or without your period given how dangerous being friends with her is.
If you have intense pain, she's extremely worried for you and will try to help in any way she can, especially if you have other issues that impact your period and or your period causes you other issues.

Casey Jones
Once he gets it Casey doesn't care for the exact details, all he needs to know is when he needs to be involved. Then he's actually really helpful
Usually gets too embarrassed to buy pads for you so he asks April to do it for him, if she refuses he awkwardly makes his way over and will be red the entire time he buys them.
He will begrudgingly be mushy if it means you'll feel better, but also reluctantly leaves you alone if you prefer being alone, he's complicated when it comes to you.
Tends to try to make you laugh or smile if you get sad, but fails to realise that the flood gates of hell spill over with unholy blood whenever you do laugh too hard.
If you're someone with less blood and or pain he'll be asking once every few hours if you're okay, every month is the same, he never learns that you're going to be fine, or that you don't experience too much pain, but it shows he cares.
If you have intense pain he's next to you always helping and at your beck and call, he's fine with skipping out on time with April or the turtles because he doesn't want you in pain.
This has been in my drafts for a little over a year, I've only just got the strength to finish it (。ŏ﹏ŏ)
