Is it okay?

Kayla • 17 and proud to be a teen mom. I wouldn't change it for the world! He is my little blessing❤️
I'm 20 weeks and I'm still not fully showing... I can suck in my belly.... When I do, i can see a little bump but it's not much.... At times when I'm laying on my side, it'll feel squishy. Also, a little below my belly button, it's hard and near my belly button it's squishy. When I don't suck in, it's still hard and firm. Is it okay that I'm 20 weeks and haven't "popped" or even started to fully show???
