I'm thinking about trying to incorporate OPKs alongside my temperature charting this month. We're just starting cycle 4 (I'm CD3 now) and I want to try to make sure we've got the best timing and the most information possible so that hopefully this can be our month.

I don't know a ton about using OPKs but I know a lot of people around here use them. Does anyone have any recommendations for specific brands that seem to be better than others? Or tips for using them?
