Opk question help!!

Karen

This are my opk results this cycle. Last cycle I had positive opk by cd 19, this time I had almost positive on cd 15, have been testing since and all negatives, no second line at all. Im on cd 23. Could that mean I didn’t catch my lh surge on time? To me was negative on cd15. Second line wasnt strong in color as the test line. Do i consider it as positive? Please help. Will keep testing but I’m already on cd23. This wasnt my month I guess.....also I havent had pain/cramps/ewcm. I remember last cycle when I had my opk positive later that day I started feeling cramps on my ovaries/lower stomach. Nothing this time. Thanks 👋
