I just received news that I tested negative. We underwent a donor cycle. The donor is 22 years of age, 15 eggs were retrieved, 13 were mature and 12 fertlized. On day 3 we had five at 9 cell and up, 3 at 8 cells, one at 7 cells and the balance under 6 cells. We asked for a day 5 transfer. On day 5 we had two grade 1 quality blastocysts, which we transferred and on day 6 we froze another two grade 1 blastocysts. The two couples that underwent a shared cycle prior to us both were successful with this donor. What went wrong? Is it the sperm? In addition, while preparing for the transfer we found out that I have a polyp (the doctor says its one and small, however, this was concluded using a 3D ultrasound). We are devastated. After nine years of this we are reaching the end of our rope. What do you suggest we should check? I did have all the symptoms, cramping, my breasts increased by almost one cup size, constantly thirsty, irritable etc.
