I have white pus coming out of my armpit but theyre is no bump previously I had bumps come out but this time its just two open pores what does this me?

Hydradenitis. The most common cause is something called hidradenitis suppurativa. This isn't dangerous but it can cause a discharge and at times this can smell. It's a condition that tends to get a little worse before stabilizing. The other possible cause is something called an epidermoid cyst, not dangerous but can intermittently cause a white pus to be secreted and sometimes painful.
