Please reassure me it's possible!

Crystal • Love Jesus! My family! Sever endometriosis. 2 teenage boys. TTC for 17yrs.
Here's a little background.. As a teenager I had 2 healthy boy's who are now teenagers (17&16). My husband is 37 I'm 34. He's not my boy's father we have been married 5yrs. Since I had my youngest 17yrs ago(this Aug) I have NEVER been able to get pregnant. I have taken the max dosage of clomid/ I have taken the femara shot and the ovidril shot with NO outcome. I have had 1 cyst ruptured and removed that's when they noticed the endometriosis(2006) I had the dye through my tubes they were good then. I had another laparoscopic surgery in 2012. In 2013 I started see a Reproductive Endocrinologist everything is fine with me I ovulate fine & all levels were good, hubby a also had sperm tested his levels were good. In 2015  they removed endometriosis & few cyst, The dr stated he was going to try and fix my rt tube because it looked damaged from scar tissue but when he got in said he was leaving it. ( if it would help my chances why not remove it?) Still NOTHING!  On 3-31-16 another dr has started me on the lupron depot 3 mo shot. So now it's WAITING again!  I would just like to hear positive similar stories. This is VERY disheartening, I pray everyday that God will bless us with at least one of ours together. 
If you have endometriosis and got pregnant, how severe was your endometriosis when you concieved?
If you had to have one tube removed, how long did it take to concieve? What obstacles did you have to go through?
God bless y'all and thank you for any input.
