2 days to try and have a baby

Laurynn
Hi girls
​I need a question answered if anyone can help you guys seem to be very cluded up! 
​My boyfriend works away In the week, I get to see him at weekend( and maybe 1 night in the week if I drive up to him)
​What happens if my ovulation day is in the week and I'm not with him? Does that mean I miss that month of trying and have to hope it falls on a weekend next month? Very confused about the ovulation days and when you can get pregnant, unfortunately for us we have been trying for a few years but only now are we ( I) using ovulation test daily to work these out
​Any advise if anyone is in the same boat as us!
​Thanks :-)
