Please help!!

Hubby has been away all week (this is fertile week! Last day tomorrow) have been taking opk anyway to keep track of cycle for past two months.thought I had my surge sat as both lines were similar but today took opk and the test line is very dark compared to control does that mean I've ovulated already? Hubby returns tonight but I'm nightshift was wondering if there would be any point bd'ing tomorrow when we see each other? Not sure if we'd have much chance so be out this month!any advice would be great!
