I was sure that we were missing something. So sure that I insisted on using a guarantee program. I didn't want to lose any money when I knew that DE wasn't going to work either.
Adding to my anxiety was that all my ovarian test results were only borderline abnormal.
My first DE cycle was a c/p making me even more sure that we were missing something. I did insist on some extra testing at that point even though my RE thought that we just got a bad batch of eggs. I tested positive for a clotting issue so we added lovenox to my protocol for the next go.
Second DE cycle we had better embryos to transfer and it worked. I really think the better embryos is the reason for the success and not the lovenox.
So, in my case, it looks like my gut was wrong and it was just my own fears convincing me that it wouldn't work. Good luck to you!!
