Have a popped abscess in my bellybutton which smells really bad and first had green puss come out followed by green puss tainted red, ?

Untreated infection: Foul smelling pus is a mixture of bacteria and your body's white blood cells there to kill it. After draining it, there will be some blood mixed with the discharge as the healthy surrounding tissue is irritated. You need to be seen by your doctor for an antibiotic to prevent further spreading of the infection.

Odd location: This is a strange location for an abscess. You need to see a doctor about this to make sure its nothing serious. I wouldn't wait until next week. Hope this helps!
