I've had mine pierced for over a year and it just looks like a stretch mark
Mines been done almost 2 years and I started to get the "red mark" in between the 2 holes it started to look pretty bad I almost took it out but decided to wait and now I'm 35 weeks and it has already faded a lot. So I'm hoping it will go away completely after birth. It's barley noticible now like I'm the only one that actually really notices it.
I don't know if it fades. I had had mine out for about a year and since i got mine so long ago I still have the hole, well when i got pregnant last year it started getting really red as it stretched, my daughter is now 8 months old and it's still a bit red around the hole. I'm pregnant again but still early so it will happen to me again with time probably.
I have it right now! I actually got mine pierced in January 2015. I had no idea I was pregnant at the time. Until a good week after I got it done. Once I hit 20 weeks I had to take it out because my belly button was stretching and thining out too much. I now have a tip of the pinky size red scar around the top part of the naval hole. I'm now 26 + 3 and it's still not fading.
I have one now, I heard it fades after you give birth.
