Need to vent.help

Ok so the last day my husband and i bd was yesterday Sunday and I should be ovulating this week. My husband has left out of town for working reasons and I’m afraid I will ovulate during the week. I am taking the ovulation test strips every day around 7 in the afternoon. I will be seeing my husband until Saturday and like I said I’m afraid of ovulating before that. Once I do get my positive ovulation test how long do I have to bd? Also is there any way that any of the sperm from Sunday might still be alive waiting for the egg?

I really hope this is my month to conceive please pray for me and send me all the baby dust You can.. it’s hard since my husband is working up north and i don’t always have the availability of bd when ever I should be. I see him every 2 weeks during 2 days and sometimes more often once a week but only on the weekends. The struggle is real but I know that it’s not impossible.
