Ladies advice

What's a great way to get pregnant in 6 months or less? What's the eating plan? The sex? The exercise? The everything. I'm up for anything? Just ready. I'm mentally ready to get pregnant. I've been trying for a 1 and half almost 2 years. I've tried almost everything I know to get pregnant. Seen a specialist. Hubby has low sperm count, low sperm motility, and oddly shaped sperm. He has done semen analysis 1 time. I have done test. Everything but HSG. Need to get that done when I have money. Everything on my end looks fine. Just need to know. Should I change my diet? Exercise more? Have sex less or more?
