Based on what you're describing, I think it's worth you at least consulting a GYN who specialises in endo. You really want someone who knows a lot about it because A) they'll have the best experience to know whether it's worth doing a lap to investigate based on your symptoms, and B) they'll be the best surgeons to do that lap.

I had extremely painful periods (doubled over in pain for 3 days each month and over-the-counter pain meds did absolutely zero to ease that pain) and for 10 years I had Drs tell me my pain was "normal". It wasn't until I saw a GYN who specialises in endo that anyone took me seriously - he immediately booked me in for the surgery and found severe endo. I also always had diarrhoea during AF and it turns out that was due to the endo covering half of my bowel - it has done so much damage that I was told I will need a bowel resection one day (long, painful recovery). The endo had also encased one of my ovaries and is likely the cause of my DOR (diminished ovarian reserve).
