My wife and I started the process of IUI in January. I just got my period again after my fourth round of IUI (two rounds with femera and two rounds with injectable meds). This last round I had three mature follicles at insemination, and we were convinced it was going to work. We are both incredibly frustrated, and at a loss for what to think because all of the initial testing I had when we started the process came back perfectly normal (bloodwork, dye test, saline sonogram). This was our last attempt before switching to IVF because we are concerned about running out of vials, we started with 10 and now only have 6 left for making our whole family (my wife wants to be pregnant at some point as well). We have heard stories from another couple who switched donors when they were unable to get pregnant, and then were successful right away with a new donor. Wondering if anyone has had a similar experience? Or if anyone can say they’ve had a successful pregnancy with donor 15554?
