I am a professional piercer/tattooist/scarification specialist and I just want to tell you this - immediately leave your piercing alone and take whatever metal/acrylic thing you have in there OUT. That's extremely unsanitary. A cheap piercing is not worth the infection, trust someone who knows from personal experience.
You already asked this question. And the correct asnwer was already given. But, here, let me repeat it for you.... Stop. Go to a professional. You're only going to make it worse, risk infection, and maybe a trip to the ER. The correct answer won't change no matter how many times you ask the question.
Listen i agree with them above. Take it from me doing your piercings yourself is very very dangerous! You can get a awful staph infection, or worse you can damage you belly button and not beable to ever get it repierced. I pierced mine an it ended up rejecting because it was not pierced right. The best thing to do is take it out and get it done right. They are fast you dont even really feel it.
