Belly piercing help. its bleeding!?

Ok so I'm 15 and I got my belly buttoned pierced by a friend. It hurt a bit I guess, but 15 mins after she was done, it started to bleed a little so we washed it off. Once I got to my next class I kept the little towel there for the whole hour of class time. Then on my last class while I was walking with my other friend, I was gonna show it off to people and the first person that I showed, yelled. I looked down and saw blood coming out and it was making its way down my stomach! So I spent almost 30mins in the restroom cleaning my self up. I let my friend pierce me cuz she did her whole 2 ears, toungue and lip and some girls dimples, and 3 other girls belly buttons so I said "why not?". Well I went to the nurse and she put Hydrogen peroxide..idk if that's what its called, and this Neosporin gell on me and it stopped bleeding. Then once I got home it started bleeding AGAIN! And right now I put some After piercing lotion that I have when I pierced my ears and idk if this'll work. I no I should have done it professionally but she did it for free. And I was wondering if any of you know how can I make it stop bleeding , how long will it take to heal, and if my After Pierced lotion is anygood? Its not bleeding as we speak but I'm worried that later on in the day it will..just let me know what's up with me. My friend said that I bleed cuz I kept shaking while she stuck the needle is wich is kinda true. I was scared. Or idk if its cuz of what she said or the fact that I'm moving to much as in walking and sitting down and getting up
