Hey ladies, help please! This is the most I've gotten for my OPK this cycle. This was taken on day 14. Day 15 showed nothing. Today is day 16. I know that the lighter color is supposed to be a negative. But I also just learned that I'm supposed to be testing in the afternoon. So could it be that this pic would have been a positive if I had waited until the afternoon to take it? Or could it be that this is just a surge and I'm going to ovulate later? I'm so confused about when I ovulate. I have 28-29 day cycles.
