Just had my egg collection today - got 7 which apparently was expected given my age (40) and my Amh levels. Should any fertilise I'm really confused as to how many to transfer. Basically, we already have a 7 year old daughter and dh doesn't want any more. He's agreed to go through this because he loves me but we both absolutely do not want twins. I also feel like I'm treading on egg shells as he suffers from depression and I'm concerned about how all this may affect him. I know our chances of success are slight anyhow, but I'm battling between doing what is probably fair (1 embryo) and what will boost our chances (2). Any advice?
