To Transfer or Not to Transfer🤔

Hello! I am 38. I went through ivf in Feb of 2017. Froze 6 embryos and then transferred two of those a month later. Gave birth to a baby girl in December of 2017!

Fast forward to this summer....I transferred a 4AA embryo on 8/4 which failed.

I now have 3 embryos left. I am really torn on whether or not to transfer another. I would love another baby but I am SO fearful of another failed transfer. I am afraid my age had something to do with the failed transfer last month and that I’ll be setting myself up for failure again. Any advice? Success stories from anyone in a similar situation?
