Endometriosis

After trying for over a year and doing hormone treatment for TTC and being diagnosed with PCOS by my OBGYN. I finally saw a specialist. He did an ultrasound and found out I have a septate uterus and I need surgery. He also said I’m more like having endometriosis than PCOS.

I know everything about PCOS after a lot of research but I know nothing about endometriosis. Has anyone else experienced this and had to have surgery? When were you able to get pregnant?
