Hi and Welcome!
Sorry for the delay on replying to your post...
I have found that a huge "trigger" for a lot of peoples migraines/head pain are HORMONES so it could be menstrual, menopausal, having a baby, being pregnant etc.
I think you should talk to your doctor and work to find a preventative or even an acute medicine to take when the hormone levels fluctuate. You shouldnt have to just "live with it"
