I was also wondering when is the best time to use OPK?? I work all day (9 - 5) and didn't really want to pee in a cup at work!!

Is it better to use one in the morning, or should I use it after work (about 6pm?)

Also, seeing as I am on CD9, when do you think I should start testing with OPK? My cycles are around 30 days (last one was 34 days, one before that was 30 days).....
