Birth control, tubes tied and endo.

I found out after not having sex for a year and taking my birth control without a break (period) that I had endometriosis. I was then prescribed a low dose birth control pill but even then sex was very uncomfortable and periods were heavy and I never seemed to clean out because it was always dark brown and black blood. I'm on my third baby and I wanted to know how women woth endo felt about different birth control option or even getting "fixed." My husband is against me getting my tubes tied but I don't want the side effects of birth control or risk getting pregnant again.

If any of you have any advice, experiance, opinions pear let me know
