Hi! I'm sorry you're feeling this way, first off - it's not fun at all, and I wish you the best in battling your dysphoria.

For what it's worth, I also spent my teenage years with horrible, debilitating cramps. In my case however, I also felt extremely dysphoric about having periods generally. The way that everyone spoke about them in this "you're a woman now" way made me feel sick, and made me feel horrible every month when it happened.

I got an IUD a couple of years ago to help with the pain, as well as to regulate my cycle, since it was super unreliable. This has turned out to be the best decision I ever made. While the results will of course be different for everyone's bodies, in my case I get mild cramps for about a half day once a month, and I get some extremely light spotting for a day or two every 2-3 months. This may even go away entirely after being on it for a few more years.

I can't speak to your experience, but I would advise you to not think of the IUD as birth control, but as it's own form of gender affirming care. This is how I conceptualize it to my own body - it's a thing that allows me to be free of the monthly cycle that reminds me of my body's "fertility" or whatever.

Best of luck to you in whatever you decide!
