My periods are this bad as well. Thankfully I now keep track of them using an online tracker and make sure I have enough Ibuprofen, otherwise I'm completely incapacitated and end up vomiting, fainting, etc.
I strongly suspect I have endometriosis, especially since an aunt probably had it (the family "don't speak of it" but she had some sort of neurectomy due to intense period pain) and it can often run in families.
So far I've discussed it with
two doctors, was told variations on "Lots of people have really bad cramps, just get over it!" and they generally acted like I was a malingerer. I'm getting a new doctor soon (hopefully in the next week) and it's one thing I want to discuss with them. I'm sick of having to take more than the recommended safe dose of Ibuprofen just to get the pain down to a level where I don't throw up from it. No matter what those doctors said, it is NOT normal and the only other person I've met with period pain this bad has been diagnosed with endometriosis.
I'm apprehensive, though, as from what that woman told me, where I live they tend to avoid surgical solutions for endometriosis, and instead focus on heavy doses of estrogen and progesterone. Obviously I'm leery about that because I'm trans, but aside from that, my reading indicates that estrogen frequently makes endometriosis WORSE! And even though it's probably unlikely, I worry they might decide that pumping me full of female hormones is more important "for my health's sake", and refuse me testosterone when I try and get it...
Then again... it's also possible that if it
does turn out to be endometriosis, being FTM might help encourage them to suggest a hysterectomy for me. I'm not too hopeful since everyone tells me the doctors here will do just about anything to avoid giving someone a hysterectomy, or even a laproscopic surgery to remove endometrial growths (it's "too expensive", though of course you can go private), but... I'm trying to remain positive.
I just want a hysto so badly. I've wanted one since I was about five years old

I always had dysphoria about having a
womb inside me even before I really considered the gender-related significance of that. And not only do I not want it, nor want to ever use it for its intended purpose, but it causes me extreme pain. Just get rid of it, please!!
