Is my nose piercing infected?

I got my nose pierced a little over a week ago.. I clean it regualrily with sea salt and water.. the last few times cleaning the inside though, has made it pop almost all the way out, i have an L shaped stud by the way so it shouldn't just pop out like that.. but when i pushed it back in it was oozing yellowish clear gooeyness that hardens around the inside stem of the stud, and around the jewel of the stud.. is that an infection? it doesn't hurt much when i fix it back to place, or when i clean it.. it stings a teeny bit when i clean it but thats it.
