i got bump on my pus

So usually when I'm shaving and I get bumps from ingrown hairs and I just pluck it and keep it going. So recently I did just that and it was really hard to pluck the hair but the bump didn't go away like the rest, it hurts and it's hard and about a centimeter high now, I can feel it through my cheerleading shorts and it's scary 😨 I'm that point after my fertile window and before my period and I don't want to have sex and a guy sees that(Not that his opinion matters, it just makes me uncomf)!
