to the experienced preggie mommies, I'm 31 weeks still no linea nigra and belly button still innie, normal ?!

totally normal, not everyone gets it! it's a genetic thing, just like stretch marks

although my innie is still a innie its not as deep of an innie as it used to be lol..but to normal people its an innie..I wish it would pop out I think that's so cute haha..and my linea negra barely start showing too..and I'm 32

My belly button never popped and I had a very very light line

I have a line barely it started and took a detour then just stopped and my belly button is just kinda flat it doesn't have really any depth.. this picture is a few weeks old but my line hasn't changed
