Changing Migraines/Symptoms

Is it possible or has anyone had their migraine head pain change? I have been VERY fortunate in the past couple years to have had a SERIOUS reduction in the frequency of migraine head pain. But I still seem to get a lot of what I associate with the auras I would get. I get vertigo, blurry vision, sensitive to sound and light and smells. I get brain fog. I will sense a strong head pressure and KNOW there is a migraine-a-comin.Literally ALL the symptoms I would get prior and during a migraine. But often I never even take my Maxalt and it never progresses to the pain.
This happens more often than not these days.
I did have some really bad days the beginning of July where I had about 10 days on and off of all the above AND pain. That was weather/hormone/stress ... you name it.
Is this normal? Or does anyone else experience it?

Not that I am complaining! I feel very blessed to have gone from being someone who had 7-12 painful and debilitating migraines a month to maybe one a month - if that - and even go months between the pain.
