You are very specific about the drugs but not about your migraines. Pills is NOT a solution from every problem we face in the life. A ton of things matter when it comes to migraines, it could be as simple as your daily morning coffee, if you have had a concussion, your lifestyle or even your food habits (like daily Chinese takeaway or fast food).
First and foremost, keep a headache and food dairy. Note every possible things in as details as possible. You sound like a female, record your menstrual cycles as well (Hormones affect migraines). Read up on the other threads where I have posted some information and follow the general advice.
What abortives do you use? i.e. medications to stop the migraine when you feel like its coming. Is there any? If not, ask the doc to give you one. Topamax is certainly not good for someone of your age. In just 8 months, my speech was slurred and my memory was affected. My neuro doesn't agree to that happening in just 8 months but this is what I experienced.
Your headache and food diaries are VERY important. Within 3 to 4 months you will have enough data to figure out your migraine triggers, if any. Take this diary to a headache specialist (NOT neurologist). Find one in your neighborhood.
Your age is a very critical factor is medicines prescriptions and being a female of soon-to-be child bearing age complicates the matter even further. Read up some migraine books.
