TWW is killing me!!

Omg! This TWW is not the business! I'm 8dpo but I feel nauseous throughout the day, out of no where I'm starving even if I just ate, I have dizziness sometimes, my boobs are a little sore, my body is so freaking hot I wanna jump out of my skin and the last few days I've been having these sweat spells. It's like I'm taking a shower in it. Never sweat that much in my life, EVER, and I've felt pricks or pokes in my lower abdomen. I think I'm prego but im scared to think that and get a BFN!! Anyone else? Any TWW buddies?
