chances of being pregnant

I convinced hubby to have unprotected sex for two days, but I'm worried that it's not close enough to my fertile window. My calendar said I had a 6.8% chance the first day and 7.8% chance the second. I would like to just try every day but he has low-T so that's not an option. Has anyone gotten pregnant with the same odds?
