Candidal vaginitis. Without seeing and examining this and knowing what else has been going on cannot really tell, but it sounds as this has been infected. If you trust your doctor, watch this heal and if it gets any worse go back and let them see it again. Good luck.
See doctor. It is unusual to have persistent umbilical drainage, and you need to be evaluated by your physician, who can examine the area, and perhaps perform appropriate tests to find out what is causing the drainage.
