@glitterbag,
It is no longer recommended to use alcohol to clean your ears after getting them pierced - I used it, but when my daughter got her ears pierced a year ago, I found out differently.
That being said, make sure you get behind the ear and all over when you clean them (hopefully you are using a solution recommended for cleaning pierced ears) and turn/twist the studs. If you are worried you can ask where you got your ears pierced or a quick call to the doctors.
