Thanks for the reply - great nudge on the details so the pattern of fail changed most times for all of the cycles I had good egg collections and I always seemed to respond well to the injections it all went wrong from transfer day . The first few I started to bleed 4 days after embryo transfer so each time they did something different like increase the pesserie dose then after the second failed round I had daily injections of the pesserie that I did in the muscle in the tops of my legs(bloody killer) this was to try and keep the lining thick. For the next 2 cycles we did this and still a bleed came a few days after implantation. The following cycles were again diffent and supported with EVA which at the time was basically cctv for the development of the embryos ( what was apparent for the next 3 cycles was that only 1 or 2 embryos were good to transfer even got to blast fir a few but the remaining never got to a stage where they could be frozen . Also had implantation glue for the last round and a procedure where they scratched the inside walls of my womb to create the freshest cell environment to improve implantation- the last cycle I did manage to get to day 12 before test day but again stated bleeding just before. In a nut Shell based on the money we had spent and my body feeling punished we stopped after 8 times. The consultant said another round could identify the quality of the embryos or they could investigate the reasons of defragmentation but it would be a benefit for us to consider other avenues. Top line is it’s either the lining of my womb or the embryo quality or the dna not being great is the unexplained reasons for them all failing - phewww bet you wished you never asked now lol🤗
