staph????

i noticed it two days ago but it’s on my hip area so i’m not sure how long it was actually there or what it looked like in the beginning bc when i noticed it looked like this. i don’t think it’s an ingrown hair bc i don’t shave here. it hurts SO BADDDD. puss comes out 🤮🤮 im 15 weeks pregnant so im a bit worried i plan to go to express care tomorrow. anybody have any ideas on what this is & any advice?
