Looked it up....Its a dark line or discoloration of that abdomen seen in pregnant women.....So its skin!

Well I believe (dont quote me tho lol cuz I could be a little off) that is is a dark line of miscoloring of the skin. But I have noticed many women who get it tend to get a little hair there as well.

Haha kari...You said almost exactly what the medical dictionary did! Smart girl! Lol

Lol! Yah its a dark line that goes straight down ur stomach. I got it, but its very light above my belly button and very dark below my bellybutton Lol!

~heather ryan and mackenzie

Supposibly most preg girls do. I dont have it tho~ but I am getting a few tiny stretch marks on my belly. Ugh and only 2 weeks and 2 days to go!

Kari, I think you're right. I have it lightly right below my navel. And you are lucky with the strech marks, cuz I think they are about to have a feild day with my tummy. I got some a few years ago with my growth spurt, and I noticed that on me they tend to come up as a little irritating sore, and two weeks later it is a full blown strech mark. This sucks, but I know that if you get them early mederma really works.
