Belly button discharge

I experience a belly button discharge, from three days time. Sometimes yellowish and sometimes dark in color and smelly. I can also see a small clot of pink color exactly at the bottom(not on the wall skin around). Painful when touches it. I am currently not at a close proximity of a doctor. Please tell me what this can be and how risky will it be. I wash my belly button twice a day and make sure to keep it clean. Please help me.
