A very needed question about navel piercings?

Last weekend I got my navel pierced..On day 7, it stopped hurting and on day 8 it got a little tender but not like before.. I wash it with softsoap antibacterial each morning and night and I also use h2ocean purified salt water on it as recommended by my piercer so I do not think its infected and I have no symptons of infection. I also move it uo a little when I wash it so I dont get the crusties caught?Could it be the soap that made it tender?
