am I pregnant?

I'm four days late on my period. I've been getting hot a lot like a fever, especially at night. Moody, my boobs are tender, but not as swollen as usual. And I have no cm except for a small amount here and there. I've also been dizzy all week. When I tested two days ago it was negative. I'm scared to take another test and it be negative:( we really want a baby.
