2 IVFs with PGD and neither worked. Why?!?

I don't understand why this happening to me. I'm so depressed. I stupidly thought if we did <a href="https://glowing.com/glow-fertility-program">IVF</a> with PGD and only put chromosomally normal embryos in, it would work. But it didn't. Twice. Why not? Lining was good, hormone levels good, everything seemed perfect. Can't believe $30,000 just poof disappears and nothing to show for it except weight gain from all the hormones. It's not fair!!!
