Idk what’s wrong with me

My cycle is an average of 32-34 days. My last cycle lasted 52 days then I had a normal period of 5 days which was from 12/25-12/30. Since then I have not had my period. I figured it would “skip” and month since I’ve had that happen before, but I still haven’t had my period. I took a pregnancy test on 3/8, but it was a blunt negative with no possibility of a line at all. I do NOT have insurance and I live in Texas. I want to go to the doctor but I literally can’t afford it.
