Who else feels extreme pain on period?

Elenziinha
I can't live a regular life style. I been fired from most jobs because once a month I have to miss work. My period arrives and walking is no longer allowed because I crawl myself into a ball on top of my bed with pain. My back kills me. I pass out most times. I need help to walk to the bathroom to shower. My husband has to be around me to help. This goes on for about 12 to 16 hours when my period arrive. Every month. I started with the cramps at the age of 16. Right after having sexual relationship for the first time. Now I take so much pain killers and nothing has shown why I feel the pain that I do, many test were done and until today no explanation. Anyone else feels such pain every month?
I had 3 miscarriages and 1 filopian tube pregnancy. No kids until this day 😭
