I feel defeated...

My 5 day transfer was yesterday. I had 15 eggs retrieved, 7 embryos formed but none reached blastocyst. There was one that they felt could develop so we continued with the transfer. Today they told me that none of the others were viable to be frozen. I can’t stop crying, it all seems like it’s now even more impossible. All the pain of this process and nothing to show for it. I know there’s still hope from the transfer but honestly it’s hard to stay positive. It’s been three years, I’m so tired and sad. and I don’t know what’s next now.
