Feeling too normal it's scary

Kirby • 22. Can't wait for my baby boy to get here! Hurry up August!
Lately I have been feeling so normal it's scary. I am 15 wks 3 days and I no longer feel pregnant at all! Is this normal? I have had a miscarriage in the past so I am terrified. Not to mention I don't look pregnant at all. Is anyone else feeling this way?
