feeling sick

This is a dumb question I suppose, but I woke up dizzy with a slight headache and my SO says I feel a little warm. I also slept from 9pm-9am, which is a long ass time (and the longer I sleep, I tend to wake up warm). Should I be worried? I don't really feel sick, just dizzy and I'm only slightly dizzier than my normal pregnancy dizziness. And I can't find my damn thermometer because we just moved and it's packed.
