Belly Button Bleeding Following Physical Activity

Good morning,

I am a 29 year old male suffering from obesity. I have often had small smelly secretions and small blood spills accompanied by slight pains from the navel, all of them healed naturally in a few days.

After having walked a lot for 10 days on vacation, the problem got worse, I had stronger pains when I got up and sat down, I spotted bleeding and yellowish mucus discharge, and a large part of belly skin around and below the navel had turned red.

What should I do? The doctor is bookable only as of tomorrow.

Thank you in advance
