Ingrown hair? Cyst? It hurts so bad 😖

So I'm 38 weeks pregnant and hubby helped me shave the forbidden fruit since I can't see lol well a couple days later when I wiped it was sore so I reached back and felt a lump, I gently squeezed it and it burst it was a mix of blood and pus so I assumed ingrown hair

. Well it's been a week now and the lump is still there and still painful, it doesn't not have a head on it. Idk what it is but I want it gone. Any input on either what it is or how to get rid of it would be fantastic!
