My infected bug bite popped?

I was bitten by something and it resulted into an infection. I went to the doctor two days ago and she gave me antibiotics and specifically warned me not to pop it. Today i was wearing jeans and I felt the bite pop underneath the gauze bandage i had wrapped over it. It was been 9 hours since it popped and it will not stop bleeding or oozing pus, I'm still taking the antibiotics and I placed some band aids over the open wound. I'm worried about what this means and what are the next steps I should take.
