[asdfghmk]

i'm 15 years old and i had a pain in my side for about 3 weeks and i went in for an ultrasound and they said i had an ovarian cyst that twisted.i had to have emergency surgery and luckily i got to keep my ovary, but they went in through my belly button and i had it pierced. i've had it pierced since april and from what i can tell the hole is still there they didn't tell me how long i had to wait before i could put it back in so does anyone know when i can ? and how long can i keep it out before it closes ? i really don't wanna get it repierced
