Is it ok to take a bubble bath after getting your belly button periced?

I would hold off on that for at least a week or two. Baths collect a lot of germs and thats not good for a new piercing. So try and stick to showers. If you dont have a shower, wear a water proof bandage over it if you can and rinse it with the sea salt+water after bathing. You also dont want to get any soap on the piercing while its healing so the bubble liquid might irritate it.
