I suggest try taking Iodine & Vitamin K with the d3 regimen... Vitamin K helps push Calcium into the bones . while Iodine helps the Thyroid function, there's a bit of search done on Thyroid and headages. Iodine & K can lightly supplement decreasing Calcium levels in the blood
https://www.thyroidcentral.com/hypothyroidism-and-migraines/ (or google Thyroid headages.)
Thornes Vitamin k2 has 15mg = 12,500% per 15 drops ( 1 serving) a bit pricy. , over the last year after I started taking Iodine with K during my d3 regimen, there's been a meaningful decrease in episodes and and pretty much the god dam pain has plummeted from 7-9 to 3... This could be due to other factors, but still worth a shot.
****** Highly suggest you guys read ****
