Chances this month?!?

I had a +opk yesterday afternoon but I wasn't able to BD with my hubby until this morning as he's been away, the last time before that was Tuesday. Yesterday was the day Glow said I was at peak fertility. A bit gutted as I feel like we've missed our chance this month and wasted it! Am I already out before the TWW? With my first pregnancy, I conceived on a 'month off' so I had no idea what the correlation was between +opk and BDing!
