On the brink of giving up

Last month I had surgery. My doctor performed a laparotomy to remove my endometriosis and unclog my Fallopian tubes. Yesterday, I had my post-op appointment. He told me only 20-30% of my fimbrae on both tubes are active, which can lead to an ectopic pregnancy. For now he doesn't want me to TTC until he does an iodine test to make sure my tubes didn't close. Has this happened to anyone? I'm trying to stay positive but 20-30% is such a low number.
