Is it normal to have a bump, with white stuff inside after a month of mole removal. (photos)

I had my mole removed about a month ago, and it seemed to be healing just fine. Within the last week, I’ve developed a bump, with white inside it. It has not popped, I put neosporin. It seems as if the mole is growing back because now I have the same bump, except this time it is skin, and not an actual mole. What should I do? Will the mole grow back? Should I try to pop it or let it be?
