One ovary left and severe endometriosis...

When I was 18 I was diagnosed with ovarian cancer, my left ovary was enlarged to be about 7lbs. So they removed it and sent it off for testing after that I found out that all the cancer was in that ovary so I got lucky that they caught it in time. I go for check ups every 6 months and get blood work every 3 months. Still cancer free just a few scares along the way. In October 2013, I was diagnosed with sever endometriosis pretty much everywhere on my tubes, walls, etc. my fiancé and I have been told so many different things on if I can conceive or not. I had one pregnancy in October of 2009 the same year I had my ovary removed but I had to induce a miscarriage when there was no heart beat. That killed me and was rough. I grew up with a big family and have always dreamed of having my own little bundle of joy. I just had surgery again two weeks ago to burn off more of the endometriosis. I take birth control pills to keep the endometriosis calm. I am so scared I won't have at least one child of my own. Is there anyone out there that can relate or have advice. Please help me through this.
