Endometriosis

I'm only 16 and have been dealing with heavy periods and extremely bad lower back pain since I was about 13. The doctors consistently told me that the back pain was just growing pains. They then did tests and couldn't find anything physically wrong with my back but instead that I was anemic. About a month ago, i got a sudden pain in my pelvis that lasted for over 2 weeks. I went to the doctors and finally had a good nurse who suggested that I may have endometriosis. Since then, I've had more blood tests (which have came back clear) and today had an transabdominal ultrasound which showed that my that I had a split in my uterus. I was wondering is there any other tests or anything that can be done that will indicate that I have endometriosis? Also, has anyone else experienced the same as me?
