17 fertilized, 5 made it to blastocyst

Ro

Hi all. First time doing <a href="https://glowing.com/glow-fertility-program">IVF</a>. We had 17 follicles, 17 fertilized which we were excited about but only 5 made it to blastocyst. The doctor said they like to see half but this number is still fine. They’re now being genetically tested for 2 weeks. Should we be concerned that it’s less than half? Did anyone else have similar results and had success? Thank you!
