I feel like I should know this but no amount of googling seems to give me a clear answer. I'm using an OPK and can never figure out the timing of it. When I get a positive, does that mean ovulation is imminent or that ovulation is occurring at that time? And once I get a positive, what should the timing be for getting *it* done? The directions seem to indicate that a positive means there's some kind of 48 hour window but what if you only test once a day?

I also rely on CM to let me know when ovulation is happening but can't figure out if once CM presents itself, that means it's already starting to be too late or if that's just the beginning of the process.

I'm not sure why but I find this whole thing a little confusing!
