Yes. My doctor says it has nothing to do with the cord. Just that the area around your belly button is the only area of your stomach that doesn't have an extra layer of muscle between it and your uterus. So it is more likely to be tender there.

BFP #2 8/2011 (ectopic pregnancy)
BFP #3 10/2011 (chemical pregnancy)
BFP #4 12/2011 (Abigail born 8/15/12)
BFP #5 5/2013 (Griffin born 1/23/14 with heart defects, now repaired!)
Mine is really tender too--they say it gets sore when it is about to turn into an outie. I actually am bruised around my belly button because of this process. I hope it pops soon and maybe it will bring a little relief.
