2 failed transfers. Just found out my sister is pregnant

I’ve had so far 2 failed transfers. 1 fresh & 1 frozen. We have 2 embryos left. Idk if I should do another round. We have male factor infertility and I’m so afraid that it’s not going to work again.

Also, Today I also found out my sister is pregnant. She did <a href="https://glowing.com/glow-fertility-program">IVF</a> as well and did a fresh transfer. I’m so happy for her but can’t help but feel sad at the same time. When I call my husband to tell him, he broke down in tears. He’s happy for them but doesn’t understand why it can’t happen for us.
