Should i get my belly button pierced?

im out of school tomorrow for the summer and i want my belly button pierced. id probably go sometime this week to do it. im in high school and im still kind of considering it...theres a pool party that im going to on june 11th, so would it be healed enough to do a little swimming then? or should i wait? i kind of wanna show it off but i wanna go swimming too. i dont do sports in the summer so i wont hafta worry about that..i also dont go swimming too often. based on all that, should i get it pierced now or wait?thanks!
