9 weeks pregnant and shaking like a leaf.?

i just got up and started shaking im not feeling faint just sort of out of it and shaky. I'm even stuttering a bit. i just ate some smores. and had some water so its not low blood sugar. i had a bit higher then normal blood pressure last time i was at the doctor. with my last pregnancy i had preeclampsia and had to have a c-section. is it possible that i could be getting it again? and so early? or if not what else could it be?
