Donna-paul, what type of HRT were you taking before switching to this latest regime? The thing is, if your migraines are caused by progesterone as mine are then the last thing you need is to starting using it every day. Do you know what your migraine trigger is? If it is too much oestrogen then this new regime might fly but if it is too much progesterone then it is a bad idea.
Migraine does not preclude you for taking HRT and in my case, it prevents it but I do have to keep my oestrogen levels high in order to do so.
I think you need to know your migraine trigger and work out the best HRT regime.
