The key to a healthy, problem-free piercing is the ability to regularly clean the new piercing and earring with the right materials the recommended times over the course of a day for a length of time until healing is complete (two problems right there, the time and access to proper cleaning materials), wearing the earring 24/7 for the recommended time period (another problem), keeping the general area free of contaminants such as dirt (another challenge), losing an earring or earring back, and having to take both out with no opportunity to replace (holes close up, wasted effort).
Get them done the night or the morning after you go home for winter break. You can tend them carefully and ensure healing. And ask for the pearl and diamond (or CZ) studs allowed with certain dress uniforms! There are regs about size and shape.
