Does everyone get the linea negra? I'm 34 weeks and wondering why I never got it lol

I'm brown but I didn't get anything lol

My skin tone is just brown and right now I have a really light line but as I get big it'll show more then when the skin isn't stretched after brith my belly is just dark so it disappears after. Happened with my first pregnancy.

I didn't get it last time or this time. I've heard it's dependent on your skin pigmentation.

Some women don't get it. This is pregnancy number 3 for me and I have never had during any pregnancy or noticed it after.

I never noticed I had it til after I delivered and lost all that weight. it was so light colored when my belly was stretched, but now it's like a dark color because the skin isn't stretched anymore.

I never did
