Newborn Bellybutton Discharge?

Whitney

My LOs stump fell off around day 8 and seemed fine shes now 13 days . We haven't given her a full bath just sponge baths because we wanted to make sure it was all the way healed. But it might be infected maybe? It's not red, doesn't seem to bother her at all and she hasn't had any fevers. There has been a tiny bit of discharge stuff and I'm just wondering if it's normal or if I should be worried?
