Anyone else feeling NOT pregnant?

I'm 10 weeks 3 daya. I dont feel pregnant at all. My boobs havent grown. They arent sore. No morning sickness, nothing at all. I feel normal. The only thing i have noticed is that i take one nap a day, and im thirsty alot. I also get headaches if i dont eat or drink. But i had that when i wasnt pregnant, just not as bad. I just feel like im not pregnant even though ive had an ultrasound. Ugh!
