Another setback

I had high hopes of having a FET in Dec or Jan. I've had 3 failed transfers so after the last one failed, I had a hysteroscopy that found and repaired scar tissue. Recovery from that took 2 months. Then I had a Receptiva biopsy done and it came back positive for endometriosis. So now I have to take lupron depot for 3 months to suppress the endometriosis before I can have another FET again. It hurts so much to have another setback! It's been 4 years of trying with fertility treatments to just have so much loss and no success.
