Ttc low sperm count & pcos

My partner has low sperm count and I have pcos. I’m on clomid and responding. We’ve tried 6 cycles with no success. I feel this is never going to happen. I don’t understand why this isn’t working. I’ve been pregnant before. Feeling helpless and wondering if there’s anything else we can do? Anyone else been in this position and found anything that helped? Partner taking proceive and I’m on folic acid & vitamin D.
