A month ago I had a blastocyst transferred. It was my sixth procedure. I chose DE IVF this time because on my fifth cycle we got only four eggs and one blastocyst, which was transferred. On my OTD I got a BFN. So I tried DE IVF and about a month ago we had the transfer. Still got a BFN. I switched clinics and my clinic in Kiev found natural killer cells. I'm on treatment now. After all this I'm not sure I'm up for a 7th. I'm so scared.
