Is this safe to do for my ear piercing?

I got my ears pierced about 4 weeks ago, the earrings aren't long enough and are suffocating my earlobes, and the earrings are sort of growing into my ears. I only have 2 weeks to go til I could take them out anyway- we're going to claires today to see if they'll take them out and replace them with ones that have a longer back. but i'm not sure if its against their policy, theyll probably tell me to let them grow back and try again? do you think it'd be safe to buy earrings and replace them myself at home?
