successful pregnancies with endo?

Shianne
We have our second appointment since beginning TTC in October with our OB/GYN this Wednesday. I have tracked everything since starting. We've been given the option of lap or Lupron, but she wanted us to TTC without those interventions first. I've only been treated with BC pills (which never did much anyway) in the past. 
Can anyone shed some light on if they TTC  successfully with endo & no treatments first? How long did it take and what did you do?
Also, if you did have treatments to increase your chances, what treatments did you undergo, how did they make you feel, and were you able to conceive?
I'm not sure what to ask my doctor or what to do next. I just know that hubby and I want a baby and the endo pain sucks so bad. 
Any and all advice is appreciated! Thanks!
