Is it weird to have 2 migraines in just a few days?

It's never really happened before! I get this weird fuzzy thing in my vision and it gets bigger and bigger and once that's gone, my migraines start. I've have 2 migraines in about 4 days? Is that weird or something I need to worry about? Also, the first migraine was on the right side of my head a little over my eye and the second one was on the left side of my my head. Thanks!!
