Migraine from mnthly cycle started last fri. still have dull headache, feel fine in am, worse in pm.could it be due to my new glasses?

Unlikely the glasses: The glasses usually don't cause tension type headache which is what you describe. If your menstrual cycles produce regular headaches then you might want to consider miniprophylaxis with an agent like Frova (frovatriptan) if your neurologist agrees. Other considerations would include elemental magnesium, riboflavin, and butterbur.
