Hi, male 24 here. Few minutes ago I felt something is going on with my belly button so I went to the bathroom to check, to see there is a bit of blood in it, and I didn't like the smell although it's not that much smelly. I cleaned it up with a bit of toilet paper and water but it seems like it will have more blood soon again. Why does this happen? And what else can I do before I'll need a doctor? Of course the place is always clean enough, I always take care of that specific part as it needs to. It had happened again last year I think but I cleaned it only one time and it was gone then, clean and normal. But this time it still gets some blood. Please help
