Bump on my crotch

Hailey

About a month and a half ago I got this big bump on my crotch. It became swollen and red, but I eventually popped it and it only bled. I though it might’ve been an ingrown hair, but I never saw a hair in there so I couldn’t pluck it out. Now, it isn’t swollen at all really but it is very red/purple from the blood under the skin, looking very ugly and making me self conscious. I would post a picture, but last time I was ridiculed for posting a picture in “TMI pictures”... please, anyone have a similar thing to this? I don’t know what it is
