Semen analysis - Anyone else?

Michelle • 34, DH 37. ttc #1 for 4+ years
DH got his SA results back. He has low count (18mil) and 0 are rapid with forward progression. The rest are either not moving or slow with forward progression. The urologist told him that we can still get pregnant with those results but it's been 3 years! We had one miscarriage about 2 years ago, so I'm sure it's possible, but seriously. We have had 2 IUIs and both failed. My insurance doesn't cover <a href="https://glowing.com/glow-fertility-program">IVF</a> so I'm not sure what else we can do. Maybe we aren't having sex early enough? Has anyone ever had this problem? Can preseed help? Any advice would be appreciated!! Thanks!
