I get migraines, sometimes, as part of my PMS.
I also get stress related migraines.
Years ago I tried out several migraine medicines, under the care of a doctor, until I found one that worked well, and quickly, for me.
You really do need to go to doctor and start trying different meds until you find the one that works for you. Also, keep a journal that includes menstrual cycle, foods that you eat, and emotions/stress triggers. All of these things can contribute to migraines. A journal will help you figure out your migraine triggers and you, and your physician, can help you find ways to lessen the triggers.
I always found Excedrine migraine to be not very effective - if you read the ingredients, and compare it to extra strength Excerine - if I remember correctly, they are the same drug. It is very harsh on the tummy.
I have been prescription migraine medicine free for the past two years. I watch my menstrual cycle and begin taking ibuprofen a few days before hand, and work very hard with watching my stress triggers. While I do still get one or two migraines a year, it is down from one every month, and the ones I get are not nearly as severe. I manage them with a combination of ibuprofen, tylenol and caffeine, which serves as an accelerator to get the meds into my system faster.
there are a few good websites that will help you -

It becomes a matter of trail and error to find the right medication and eliminate any environmental/food triggers.
Don't give up.
Do some research, eliminate common triggers, and see a doctor.
Migraines can be managed - you don't have to suffer.
Good Luck
God Bless
