13-14DPO..What in the world!

Sa

I'm 13-14DPO now..(taking a test later today).. but this morning i woke up, I didn't stand, move or anything, just literally opened my eyes and the room was SPINNING, just like it would when you have way too much to drink.. it freaked me out! I'm not feeling too well (sore throat etc.) So I figured it's cause I'm not feeling well so I went back to sleep, I woke up again and same exact thing happened.. what is this?! I know dizziness is a symptom, but i feel this is a lil much? It hasn't happened again, but I'm still a lil light headed, but I think cause I'm not feeling well.. anyone else experience this?
