I notice that some of us approach OPK in a different way. It seems that some of us BD on varying days i.e CD 10, 12, 14, 16 etc and others use the OPK to determine when to BD. What is actually more effective???

I personally have started BD every other day or every day depending on my stamina Chat Icon and use the OPK to determine if I am ovulating (I test late when I get home so I dont want to miss a thing).
