We have been married for 20 years and for 19 of those years have not used contraceptives. As far as I know, I've never been pregnant. I was diagnosed with severe endometriosis and have had 6 laparoscopies. However, the condition did not appear to physically interfere with conception nor pregnancy. We tried invitro 6 years ago, and were told we had an 80% chance of success. It did not work, and the doctor was baffled and could offer us no explanation. I am 44 years old, have not had symptoms of endometriosis for several years. I would love to get any information that might help us... I don't have much time left... Thanks!
