Nose piercing?

Im 16 and i made a deal with my mom that if i get straight A's that i can get a nose piercing. So i got my report card last week and got straight A's. And i just wanted help on like what i should expect and just general help. when i first got my regular lobes pierced there got infected and i got them again and then got infected again so i got them pierced again when i was 15 and they have been doing well for a year now but i think its because I'm allergic to nickel or metal but i can wear white gold! but if i get an infection should i take it out

' and is a bump like a red bump normal to have? thanks! oh one more thing, what kind of nose ring is recommended? like a screw one that curves, an L shape? which one

thanks for the help
