Menstrually related migraines often correspond to a drop in estrogen before and after your period. I started getting these a few years ago, and it's basically like clockwork, the day my period starts, but sometimes after. Every now and then I may have one another time, thus mine are menstrually related and not pure menstrual I guess, but they are usually corresponding with menses.
On the plus side, at least they are fairly predictable, so that you can kind of schedule around them. That's a big plus when you consider that other folks with migraines can't do this. However, mine are usually completely debilitating. I am bedridden or vomiting all day, can't eat anything, have light and sound sensitivity so that I'm just shut down and in a dark room all day. Mine usually last 1.5 to 2 days. Sometimes they are shorter. Some times I get a few hours of a reprieve and then back into the nightmare. I have had several trips to the ER when it got so bad that I couldn't take it, and their cocktail usually works quickly, but unfortunately can't be duplicated in pill form. I have a pretty good doctor. You need to find a headache center that specializes in menstrually related migraines or menstrual migraines.
I can't take triptans due to past cardiac issues, so I currently have fioricet and zofran for nausea. The fioricet works pretty well for me in shortening the migraines considerably, but can only be taken sparingly because it can cause rebound headaches. It is an abortive, it stops the migraine process. I also sometimes use arthrotec. Zofran used to work great, but seems not to be working so well lately, so I may have to find a different anti-nauseal. For me, the nausea is usually much worse than the headache, though the headache isn't a cakewalk either.
Good luck to you. Hopefully knowing what its called will help you to find a good doctor.
