Belly button

Ok so this is super random but I've had two kids and everything bounced back and I'm smaller then I was in high school (I'm trying to gain weight now 110lbs). This is the only proof on my body I've had kids and it makes me super self conscious (I know it's something so small but it bothers me so much). It just looks so weird from where I had my belly button pierced. I gained a ton of weight with each pregnancy so I know I should be happy and ok with my body but I cant. I've always been very insecure and I just want my belly button back
