I’m not on HRT but earlier in my peri menopause journey I had terrible migraines but they did eventually stop, so it must be all the hormones and the peaks and drops in estrogen.I'm almost convinced it's the reduced oestrogen that's causing my migraines as I've only been having them about 18m and at the time of my cycle that oestrogen is reducing. I was quite surprised that she said my migraines would potentially prevent HRT rather than be a reason to take it
