There are two very close horizontal scars just inside my belly button from an appendectomy in Oct., and then my ectopic in December. Now that I have a rather round bump, they are no longer inside my belly button and create this funny indention in my bump. Just going to consider it "character" for now. I would post a pic, but I don't know how to take one with my phone and put it on the computer
What makes your bump unique? Aside from that LO growing in there, of course!
