No. I've had my belly button pierced for eight years and never had a hernia. So I have a hard time believing that a belly button ring could cause a hernia. It can cause an infection but it can't cause a hernia.
Never heard of such a thing. I know plenty of people that have belly button piercings and have kids...

no, based on my experience
If you can't find your belly button, it may be due to a number of reasons. Here are a few possibilities: Your belly button is covered by excess body fat: If you have a higher percentage of body fat, it may be more difficult to see your belly button. You have an "outie": Some people have a protruding belly button, which can make it easier to find. However, others have an "innie," which can be harder to see. You have a medical condition: In rare cases, a medical condition such as an umbilical hernia or an abdominal wall defect can affect the appearance or location of the belly button. You're not looking in the right place: The location of your belly button may be slightly different than you expect. It's typically located in the center of your abdomen, about halfway between your breastbone and your pubic bone. If you're having trouble finding your belly button and are concerned, it's always best to consult with a healthcare provider for an evaluation.
If you have pus in your belly button then you may have a bacterial infection. Other signs include clear discharge, bleeding, redness, and swelling.
Umbilical Hernia. Not particularly dangerous, but get it checked out. You'll experience soreness and tenderness around the belly button area, and it's possible your belly button might swell and protrude a little. Usually results from injury or impact to the area.
One reason that a belly button can become discolored is because you are pregnant. Most of the time, your belly button will become darker and more prominent as your stomach grows throughout your pregnancy.
Milky white discharge is a sign of chlamydia.
A navel piercing will cause scarring no matter what. Whether you got pregnant or not.
