When I was a child, I'd get headaches with my period sometimes, but no other issues.
As a young adult, I had little issues with it that I recall other than the odd twinge.
A couple years after I had my youngest, when my cycle really returned, I started to get migraines with my periods. Then my period went weird where my cycle become really irregular, then didn't get it for 2-5 months at a time, and when I did it was random on length and whether it would light or really heavy, all with horrific migraines, and I started to increasingly get menopausal symptoms. I had some medical investigations, was misdiagnosed with premature ovarian insufficiency for 5 years, and only when I took in the NICE guidelines in about treatments did I learn that I had been misdiagnosed, my hormones were never at a menopausal level for my age, had to go through all the medical investigations again, and found out I really struggle to make Vitamin D with my skin tone and was utterly depleted of that and a few other things after four kids and previous times this deficiency was caught and I'd been given prescription strength supplement, it hadn't really worked because I was told by GPs to take a multivitamin once I was done and it hadn't been enough. Turns out there are Vitamin D receptors all over, including in reproductive organs and without it, the body struggles to use other hormones including sex hormones and a severe enough lack leads to being menopausal from my late twenties. I had a nurse practitioner go over just not bothering with the multivits as they're rarely enough for a deficiency issue, what dosage to take, how, how to adjust for my symptoms and if I miss doses. She was great.
Now, I only get my period if I take enough Vitamin D regularly. If I don't, I get significant menopausal symptoms including bad hot flushes. If I do, I get a dull headache, back twinges, really tired and irritable around day 28 of my cycles, which is usually around 1-2 days before I start though if I missed some of pills then it can last longer or I'll need some catchup doses. Then I get absolute relief when it starts - occasionally I'm just sitting there and can feel the relief wash over me, and sometimes the headache returns again at the end. My periods are also oddly a lot more clotty, which I've no idea on.
