Opk question

Julia • Trying for #3

We BDd on CD 14 am I took the opk after. I usually test out to see when my lh surge ends as I like to be as close to thinking of when I ovulate. I have to say this is the closest to ovulation we have gotten..so very high hopes..

My question is when the lh surge ends does that mean I did ovulate or am I screwed unless I track my temp?
