I had 4 embryos and so far 2 didn’t take (I fresh and 1 frozen) (all untested)

I wanted to do another round of stims to get more embryos and get them tested by my insurance is making us use the other 2 embryos before they will cover another round of stims.

I’m pretty upset because I’m afraid if I do another FET it’s going to fail. And I have to do 2 FET because my doctor won’t put two embryos in.

Anyone have any words of wisdom or success stories after 2 failed transfers
