Hey peggy!
Generally, the "right place" to get a navel piercing is on the skin on the top of your belly button. Sometimes when it is done it comes out crooked if the piercer doesnt really know what they are doing or they havent done a lot of navel piercings, so thats why it looks as if its not in the right place sometimes.
For the best results and least risk of catching on things, it should be pierced with a hoop rather than a barbell. After 6 weeks of having the hoop, then you can change the jewelry to whatever you want. In full, it should take the piercing anywhere from 3-5 months to heal, depending on how well its taken care of, if it gets injured, and how well your body takes to it.
Make sure you wear long shirts, loose jeans, and avoid bending forward too much until it is healed. I know that you cant avoid bending forward, just dont go out and do any up-down aerobics.
Good luck and I hope it comes out great!
