Lady Sores and blemishes

Hi ladies,

Anyone here ever experience sores/bumps that comes and goes every few months but are NOT herpes? I’ve been tested several times and am 100% sure I am STD free. However, after my latest pregnancy (he is now 8 months) during my pregnancy to current I get this small bump that starts off sore and eventually busts and sometimes may bleed a little or be a little pussy (when agitated) almost like a pimple pops up every few months in the same exact spot. Especially if I shave completely bald!!!

Anyone experience this and can tell me what may it be?
