Anyone else have this?

Alright ladies I have a question. I'm currently 9w5d pregnant with my rainbow.

Well I just noticed when I got out of the shower today that I have this line coming up on my stomach that I haven't had before.. no.. it's not stretch marks yet (I know what those look like, I have plenty) and I don't think it's linea nigra because i thought that was only the line going up toward the belly button. I've uploaded a picture and put an arrow to where I'm talking about. You can't see it as well in pictures as I can in person.. but just curious if any of you ladies have had this or what it is?
