I'm about 4 weeks pregnant, so I find it a bit odd that I've noticed that that dark pigmentation line going down from my belly button to my bikini line is already a little noticeable.
I've heard that this only happens in the second trimester.
I've also read that if the line does start showing earlier(like in my case) it might mean twins or triplets because of the increase of hormones, which causes the pigmentation.
Has anybody else experienced this??
