HELP 😫

Casey
I'm going away with family this afternoon and hubby is staying back to work. I've been using clearblue digital and haven't had any flashing smiley faces to show estrogen rising but been BD anyway, then BAM! This morning I get the solid smiley to show LH surge has happened.
So I BD'd last night, 12 hours ago and now won't see hubby for 5 days. Is there any chance his little fellas might survive? I'm taking my neice in my car otherwise I'd consider popping past his work for a quickie. 
Please give me some hope I might be ok and not wasting a cycle
