Opk positive or no?

So I took an opk today , I'm on cycle day 14 should be ovulating today but just not sure with this whole ttc thing . It's so complicated .we bd on cycle day 9,10,11,12,13 any chance?? It's just so light I dunno if we caught it in time ... I'm thinking I maybe already ovulated or haven't already . Really don't know anymore .. Help!!
