Someone inform me!!

So my husband and I started TTC this month, but unfortunately he was a very strict work schedule. We BD every day during my fertile window EXCEPT on the day that was most important (33% chance) and I'm just wondering if there is still a big chance I could get pregnant? I read online that sperm can live for up to 5 days, so I still have hope. What do you guys think? What are your personal experiences?
