You should probably post this on the infertility board since there are others there that know what you're going through.
But, just to let you know, my cousin had endo. She did IUIs after a lap and got pregnant on her 2nd try back in '06. Then trying again in '08, it was recommended that she not do another lap but go right into doing more IUIs. On her 2nd try, she got pregnant with twins and she is due in September. Good luck!!!
