Hi TC,
I also began getting "period migraines" when I was about 46 (now 52). There is usually a bad headache the day before my period, lasting into the second day. Then, I usually have a reprieve from the pain for 2 days. Then, the day before my period ends and the last day of my period, the more intense migraine appears. If I take asprin or ibuprofen starting 2-3 days before my period, I don't get the pre-period migraine; but often still get the after-period migraine. You need to keep a schedule of dosing. Every 4 hours, starting 2-3 days BEFORE your period.
Even with the proper dosage, NOTHING would make the after-period migraine stop; the OTC pain med. only lessened the pain. It would wear me out! I have a high tolerance for pain, but I would get so tired of my head hurting, and trying to function anyway.
A few months ago, I decided to try Pro-gest (OTC). I followed the directions and 3 weeks later, when I had my period, there was NO painful migraine. I was amazed and joyful. The next month, however, I did have normal headaches. Ibuprofen was enough to make it go away comletely. So Pro-gest and Ibuprofen helped get rid of the headaches.
This month, I stopped taking BCPs. I felt great and
all my meno symptoms disappeared mysteriously.

On day 19 of my cycle, I began a headache that lasted all afternoon and evening, so I decided to begin taking my new bioidentical sublingual tablets. The headache was gone when I woke up and has not returned!
From the research I've done, it appears that headaches and migraines are a sign of estrogen deficiency. Our estrogen level falls
sharply--down to its monthly low--in the days just before and during the period. Women like us, who usually suffer from estrogen deficiency will have specific symptoms at this time.
Obviously, by taking progesterone (the Pro-gest & now my bioidentical Progesterone) I was able to balance the little bit of estrogen I have with the added progesterone...and it made me pain free. The real test will come this weekend. If I have a period, I will be able to see if I have a recurrence of pre and post period migraines. I hope to God(dess) that the bio P. works!
Hope some of this info helps!
