Hi tahoe,
I am sorry you are going through such a difficult time. What ivf protocals are your drs using? I have endometriosis, overactive nk cells, multiple large fibroid. It took 3 rounds of ivf to finally get it right and they modified the protocal to include humira and intralipids. When i got my positive, yay, on the 3rd time, the urine hcg was positive. I think it depends on the accuracy of the test. I used first response. Most upt detect 50mui of hcg in urine the first response 25. When i did serum hcg it was around 1700.
I hope you dont give up, and your center tries to find a protocal thats effective for you! Hope this helps.
