Ovulation?? Or not...

Michelle • TTC our first baby!!
I'm on CD 17 of my general 28 day cycle. And I haven't got my LH surge yet... I got a reading today, but not a peak.. If I do get a surge tomorrow... That still leaves under 10 days of my luteal phase.. Is it too short a timeframe to even consider it worth our while? Feeling disheartened.
