Linea Nigra quick question

Imaan • Married to my best friend... Soon to be mummy... Soon to be daddy (yes I involve him as much as possible), South African.. Living in Johannesburg.

Hello ladies at what stage of pregnancy should the Linea Nigra (line on tummy) appear??

I'm 9 weeks and mine is already here. Makes me think if I'm not more than 9 weeks because it says online that those lines only appear later on?
