I just got them pierced, should they grow over soon?
Ear piercings usually take 4-6 months with good care. Make sure you clean at least 2 times a day with the provided cleaner, and don't play with it too much or it will get infected. Also... don't use alcohol on it. It will dry out the piercing and it will take longer to heal.
not very long. my cartilage piercing took about maybe 3 to 7 days after i had it for about 2 or 3 months.
