Frustrated wife

Hey all! So glad I have Glow to come to and reach out for advice and just vent to people who truly understand the ups and downs of TTC. I stopped taking my BC in July- after 10 consecutive years. My dr says that it should be fine. Well August September and October we never got a chance to baby dance in my fertile window. We work opposite schedules and it is SOOOOO hard to schedule. In scheduled to ovulate this Wednesday or Thursday and we found a way to baby dance this afternoon bc i was off work. Will the sperm live inside me that long (Wednesday or Thursday)? Also how the heck do people try conceiving when they're on opposite work shifts?!?  I guess two people working 9-5 is ideal lol
