I'm 23 weeks and I have the same exact thing. Lol can only tell when I stand up or lay on my back.
I didn't show until 6 or 7 months with my daughter. With my son I showed at 6 months.
I just started showing at 34 weeks
Lol I guess I'm not the only one haha, I just feel fat when I sit down..
It usually takes a little longer to show if this is your first pregnancy. I was tiny with my first and didn't show until 6 months and this time I started showing right away.
I'm 16 weeks and I can finally see some kind of bump, but I guess it's invisible to everyone else
