It’s my last chance how can I find affordable meds

In 2007 I gave birth to a beautiful baby boy at 29.5 weeks. At 18 weeks he was diagnosed with a tumor and given two weeks to live. My little man fought hard to make his way into the world but he just wasn’t meant to stay. 2 years ago we started TTC and spent most of our savings on IUIs. I am 32(now) and have no known fertility issue. I’ve had laparoscopic surgery to make sure. We’ve took out a loan to cover 1 round of <a href="https://glowing.com/glow-fertility-program">IVF</a> if we don’t PGS test we can afford meds. Given my history it breaks my heart to have to choose. My sons malformation was something that can’t be tested for but likely a result of a defect in the embryo. I’m trying to figure out the cheapest way to cover medication so that I might be able to afford PGS. Any information would be appreciated.
