Need some advice

Okay all you opk experts !! I need some advice or general info or your knowledgeable minds !! So as you can see it doesn’t quite look like iv reached my peak yet . But tonight if started with the ovulation cramping ! And on my right side ( my good side ) my left side has no tube ! So I am excited ! My question is does ovulation occur after the cramping or during the cramping ? Or should I probably ovulate maybe during the night or tomm ?? Trying to pin point is crazy !
