Menstrual Migraines and Hysterectomy

Hi, this is my first forum post and I hope I'm in the right area for this question. Basically, I'm having a hysterectomy for what looks like adenomyosis and, since I'm either menopausal already or very close, my doctor suggested I have my ovaries removed as well. The thinking is that it may finish off the menstrual migraines I get.

I started getting migraines immediately after a back surgery, but noticed a few years later that some of them were different and occurred right before a period. As the periods have mostly gone away now, I've noticed that those migraines are much less severe, but still cause a few days of nagging pain, vertigo, exhaustion and foggy thinking. I have been reading up before the surgery to make sure, but it seems like if mine are slowly diminishing I probably won't be hit by horrible migraines due to a sudden drop in hormones, as my ovaries are not producing a huge amount, anyway. And the menstrual migraines have been lessening to reflect that. I would just hate to have them taken out and then find I'm in worse shape when they slowly would have gone away within the next few years, anyway!

If anyone has had experience with this, I'd love to hear your feedback. Thanks!
