Has anyone else had really dizzy spells before their missed period?

I can't stand waiting until my period. I feel so weird. Today I took a nap because I felt so tired. Then when I got up out of bed I barely made it to the restroom b/c I was sooooo dizzy. I have not had this problem ever before. Along with that I can't stand some smells that I never noticed before like a cheeseburger wrapper sitting on the coffee table about five feet away. I also had some lower cramping when I lay down at night usually. If you had any of these symptoms before your missed period I'd like to hear about it, especially the dizzy spell.
