Lilly, statistics don't work like that. The % would never double by increasing the amount by double, you'd add on like half % but it's maths beyond my own ability really

It's set propaganda, which is all about reducing twins and not about maximising singletons.
If the uterus is good and you put two viable embryos back, they will both stick. One wouldn't stop the other from working, so in my case I'm maximising my chance of singleton, risking twins but not risking losing viable ones in the freezer especially when my FET uterus might be inferior.
I don't want to do IVF again either! You'll get there Lilly, I have no doubt. I'm glad that you're getting going again soon

Kitty, I hope it's less busy for you. They were moving ladies into the transfer waiting room yesterday! xx
