It's amazing to me that so many women have migraines that clearly are hormonally related and yet science can't figure out the links to help more women. Something like getting a migraine on day 15 every cycle is so much more than coincidence; same with the fact that estrogen helped in a way that hasn't been able to be replicated by something else.
It's good to know that others struggle with this too. My good friend just ended a two-week period in which she had a migraine most of the time. Honestly, I don't know how you guys do it.
