Can i take my earings out after 4 weeks?

It been around 4 week since i had my ears pearced and i really want to try on these new earrings. However when i was 7 i had my ears pearced and i had to take them out 4 months later because they got infected. Im 13 now, that won't affect anything will it? I really want to take them out but should i? Please reply soon....x
