Bellybutton peircing found out!!!!!?

so i had my bellybutton peirced for just about a month now without my parents knowing. When i got peirced it with my friend we were sure to use all nessecery procautions. i had 2 sterilized peircing needles i had gotten from my friend who had ordered them online. They were taken straight out of the box in front of me and were in separate packages. They are now making me go to the doctors as my mother is being an idiot and thinks ill develope hepititis or aids or something. They thought that i had taken it out but truthfully i am leaving it in as much as i can without it closing up. i dont want a nasty scar. It has never been infected and i have been cleaning it twice everyday. it is still a little bit red on the top and the bottom...is that normal? any ideas to get out of this doctors thing? and how long does this take to heal usually? Any ideas for how to deal with my situation at all would be much appreciated:) and oh i am 14 turning 15 in 4 months...
