Hope after a chemical?

I've been ttc for 2 years and had a chemical pregnancy last month (bfp 8dpo, bfn 9dpo). 
My cycles are regular, and I use OPKs (clearblue). We time sex for the day of and after my LH surge. 
My husband has low count/motility and has been on 25mg clomid for 7 months. 
We use preseed as a lubricant, but so far the chemical is the only glimmer of hope we've had and that was dashed in 24 hours. 
Does anyone have any advice or recipes for success? 
I let myself get excited last month, and now I'm lower than ever.
