Truck driver hubby?

So my husband has just taken a job as a long haul truck driver. He will be gone through the week and home on the weekends. We've been trying for over a year with no success so this new job significantly decreases our chances. 
Any tips on how to do it with him only being home 2 nights a week? 
I already use ovulation tests and preseed. 
A friend suggested taking his sperm and then inserting it on my own come ovulation time. Lmao I don't think that's an option. 
Thanks in advance
