What were your endometriosis symptoms?

I already have an appt with my doc set up but it’s in a few weeks and wanted some opinions/advice/other stories before I go. About 2.5 years ago I was diagnosed with an extremely tight pelvic floor (off the charts bad, the worst the PT had ever seen, etc). Did PT for about 6 months and it helped and I had no more symptoms til the last two cycles when out of nowhere I got similar symptoms to 2.5 years ago but worse, they feel more “deep”. It’s an intense pressure behind my pubic bone, in my lower back and around my hips with an occasional sharp pain here and there. Also feels like I have to urinate frequently. I get a little relief from stretching but as soon as I come out of it the pain comes back. The pain for the last 2 cycles was 3 weeks and then as soon as my period started it sort of subsided. Period ended and the pain came back full force. It’s very distracting but I can function in day to day life. I have very regular cycles (28 days on the dot), fairly light/moderate periods, and no bloating or other pains. Could this be endometriosis in disguise? Or just my pelvic floor acting up again? Or something completely different? Also, last time this happened I had internal and external ultrasounds, urine tests, internal exams and blood tests. However I know endo can’t be diagnosed that way. Thank you!! :)
