Last year I did my second cycle with CNY. My first was a fresh. Positive but, ended up a blighted ovum. My second cycle was a split at CNY but, due to the donor having a delayed period my body wasn't ready for the cycle once the donor was. My half of the eggs were frozen on day 2 (vitrification). We later did a frozen transfer of 2 day 3 embryos. One is my son that was born last January. I love CNY and plan to cycle with them again soon for hopefully a sibling. Best of luck to you in whatever you decide !
