IVF failed

I'm 29 years old. My husband and I went through ivf, bc of male factor infertility. I have no issues fertility wise.

First, my egg retrieval, my body responded so well to the meds that I had 33 eggs removed, putting me out for the count for 10 days. It was awful.

I just had my transfer a week and a half ago. Doctors were impressed, all my levels were perfect, my lining was perfect. We had 2 really good high quality embryos to transfer. He was very confident.

I found out yesterday that it failed.

Why? It feels hopeless! How could the perfect situation fail? I feel like it's the end for me, my dream will never come true.

Anyone experience something similar? Any advice? Even the doctors don't know why it failed.
