for those of you with diagnosed endometriosis can you please tell me your symptoms

here is a back ground of me:
I got AF when I was 12. originally it wasn't painful but after a few months it started getting painful. always irregular.
anyway since having DS I am finding AF is super heavy with large clots each month. also the pain is unbearable at times and I am still very irregular.
anyway since sunday I have had awful cramping with today being the worst. I am still a few days off from AF. its to the point I am doubling over and almost in tears. I have had to take nurofen plus just to try and help it but to be honest I am finding even that nots working each month anymore.
i think its time to go to the docs and demand action since no one since has ever wanted to deal with it before. even the gyno i saw in march was not interested.

anyway thanks for listening.
