when did everyone start to get their dark line on their belly?

I never got a dark line on my belly and I only have 5 days left

I don't have one and I'm 29 weeks

My first time at 15 weeks and now it came in at 11

I'm 33 weeks and have nothing, not everyone gets it

I don't have one.. I'll be 29 weeks this Saturday

I got a super faint one around 16 weeks. it didn't get any darker until 20 weeks though

I still haven't started getting mine. does everyone get it? or one of things some of us don't experience

around 16 weeks

mine started just not super dark yet my so just had to point it out 😩
