Painful hard bump on chin

I usually get underground pimples when my period comes and last month it happened, as usual. I was actually really good this time and didn't pick it. I used a clay mask and cleaned my face twice daily. It went down however, now its just a really hard, red bump on my chin. It's been over 2 weeks now and I'm not sure whats going on or what I can do? I've tried everything! More masks, exfoliating, steam, and I've been bad and tried squeezing it but NOTHING comes out. Last night a tiny little bit of puss came out but nothing else. Is it still a pimple or perhaps something more complicated? I don't think its an ingrown hair, but you never know.
If anyone has any advice or tips on how to keep it down that would be really appreciated!
