Summarize this article:

It is easier, safer, and overall a better idea. You should ideally not have a soaking bath until the piercing is through the initial healing stages, and oozing, bleeding and scabbing have all stopped. Just be careful to avoid hitting or damaging your piercing area.  Don't pull at or scrub the area.  Ideally both. The purpose of this is to rinse out any bacteria or soap that might have snuck in there.

Summary:
Take a shower instead, if you can. Shower as normal. When you're done, pat the area dry very lightly with a clean, soft towel. Rinse the wound out with sea salt water (one pinch in an eggcup of boiled and cooled water is about right) or tea tree oil. Clean your piercing thoroughly before you sleep that night using normal procedure.
