I would suggest it because you don't want to get it infected. Better to be safe than sorry
Wait at least 4 weeks to avoid infection
You can't swim with a healing navel piercing so it is best to go get it pierced when the weather cools down. Then you don't have to try not to swim, there just won't be the opportunity to.
Ahhh Yes you can.
You need to wait 4-6 weeks if done with a needle by a professional or up to three months if done with a mall gun.
Yes be sure to wash the piercings once you are done.
Yes, it is safe to swim in the ocean with a belly button ring as long as it isnt infected or has just recently been pierced.
You shouls availd the pool for minimum of 48
Your shouldn't because it might kill the good bacteria that is there to help your nose heal. :)
No. You shouldn't swim for 2-3 months. Water is FILLED with bacteria and whatnot so its horrible for a new piercing. It'll cause infection pretty easily.
Yes, you can swim in chlorine, just make sure you clean it as soon as you get out with the cleaning solution the place you got it done should have given you.
