Not sure what’s next

Not sure what steps are next I’ve had a laparoscopic surgery which no biopsy was done and was told everything looked normal, I’ve had internal/external ultrasound and everything is normal. My new doctor (she didn’t do my surgery) told me just because they don’t see endometriosis doesn’t mean it’s not there it could be a case that’s not significant and that she would just treat me as if I did have it which is birth control. In the past I’ve tried so many different birth controls and nothings seemed to help the pain I’ve started pelvic floor therapy and was told it could be “past trauma” (sexual assault) and I’m just feeling like I’m not getting any solid answers I’m not sure if i should try to see a specialist it’s just so expensive because the state I live endo care isn’t covered by my insurance it’s considered fertility treatment.
