Best time of day to have sex after positive OPK

Brittany

I’m still trying to get the hang of using the OPK’s. When is the best time of day to have sex once you get your positive? For example, If you get a positive test at 11am, is it best to have sex right then and there or that night? And for the next day after your positive, is it best to have sex that morning or night? Just want to be on it this time.
