Have I found my aura?

I was diagnosed with migraines in 2005.  It took some time to make the diiagnosis because I don't have "classic migraine symptoms" - Even when my migraines are at their worse, I have no problem with smells, lights, noise. I usually end up taking 2 doses of medication because I don't have an aura or "window of opportunity" to warn me prior to it becoming a full attack.  Sometimes I literally wake up with a migraine.

Last night/this morning, I had a migraine that was so bad I kept my clothes on in case I had to go the hospital.  I ended up taken demoral (which an internist was kind enough to prescribe for me in severe situations).

However as the headaches was subsiding and I could think clearly, I made a discovery:  Hours before my migraine started, when I laid down to take a nap, I could hear THE BLOOD POUNDING IN MY EARS.

I emphasize that because migraines run in my family - my aunt had a migraine where should could also hear the blood pounding in her ears and ended up driving herself to the emergency room.

I can at least now recall 3-4 times when I could hear the blood pounding in my ears.

So my question is - Was that because the migraine was so severe, or is that MY aura to be on the lookout for?

I am trying to listen to my body if it is possible, because my neurologist told me that people without aura are more likely to have strokes (both of my grandparents had strokes and they, along with my aunt have high blood pressure.  My pressure is normal, but I still think this could be a tell-tale sign.)

Thanks for your help.
