I just took my first of a 10 day progesterone 100 mg prescription , to be taken once every three months. I have developed a horrendous headache that stated about two hrs. after my dose.
I don't usually suffer from headaches, at all. But I have always reacted to progesterone: in birth control pills of my youth, progesterone creams, and that's a reason my previous doctor put me on this, along with Vivaran ( estrogen with no progesterone). I have hot flashes every 20 minutes if I'm not on Estrogen ( I'm 64).
Headache=progesterone?
