Just had my 18th IVF cycle, a 5day FET, which has failed. I got my beautiful 3 yr old on my 17th cycle, but was really hopeful that having had a successful pregnancy, it would somehow be easier for me to fall pregnant again. Feeling very sad. Now I'm 41, I don't think I would have much luck with fresh cycles, and I only have one more frozen embryo to try. Feeling very sad...
