No bump 😭

I’m exactly 19 weeks today with my first bean and no bump whatsoever. My abdomen/uterus feels harder and rounder, but you can’t tell I’m pregnant at all. I’m a bit heavier, so I’m hoping it’s from that, but it has me so scared and my baby isn’t growing. And this is a little silly, but I’m also stressed my gender reveal is next week and you can’t tell me pregnant at all. Just need to know my baby is growing and feel pregnant, why can’t I just pop already?!🤦‍♀️
