Need Advice

2 years ago my doctor told me I had a cyst on my right ovary caused by endometriosis. I go in for surgery there’s no saving the ovary at all so he takes the whole right ovary and he notices that there’s a cyst on my left one as well. He ends up taking my left ovary and leaving ovarian tissue. I’ve been TTC for a year and a half I have taken metformin and Clomid and still nothing. What I’m needing advice on is is it possible to get pregnant naturally with just ovarian tissue and a scarred Fallopian tube?
