Anyone else not feel pregnant at 16 weeks??

Heather
I don't feel pregnant now that I'm 16 weeks. My resting heart rate has slowed down, my stomach feels smaller, I have no nausea and I feel just... normal. I'm really scared and nervous for my scan on the 5th of January that it'll show somethings wrong :( I have bad health anxiety anyway and don't feel I have many people to talk to :( thanks for replying anyone xx
