I think I may Have Endometriosis ! HELP

My periods are super irregular ! I blame it on my Weight I'm 317 lbs. but recently I just got out of the hospital for really bad heavy bleeding and I was bleeding for about 20 days, going through super pads and tampons. I recently just got a endometrial biopsy three or four days ago, I did have spotting before procedure and then after I had some and then now once again I'm bleeding really heavy. I have not gotten my results from the biopsy yet, but I'm wondering if anybody here has endometriosis and is trying to concieve, what are your chances of getting pregnant ? what are symptoms of endometriosis? is there a cure? ect. My symptoms are heavy bleeding, irregular bleeding, and really really intense cramps
