treatment recommendations

I was diagnosed with adenomyosis some months ago. I bleed like 200 ml approx every time I menstruate and I usually have cramps. For some time I also had pain before going to the toilet (for pooping, because of the inflammation and the gases etc) and there were times I couldn’t even move when that pain came. But now I don’t have that pain, just the heavy bleeding. I was given contraceptives, but the prospect says it could cause breast cancer. I don’t really know what to do, I was given contraceptives before and they caused me nausea so I stopped. But adenomyosis really prevents me from doing a normal life, I cannot go outside for more than an hour if there’s no bathroom available where I can empty my menstrual cup. I’ve read about natural solutions but for example, when it comes to eating, I’m vegan, so I cannot eat more green hahaha. Anyways, if you’ve experienced any improvement or just want to share your experience, I’m happy to read. ❤️‍🩹
