I am on cd 19 if you consider the first day I really bleed and not spotted from my m.c. I have been doing opks for several days because my boobs have been hurting and I have been having cramps on and off. I have been getting some with partial dark lines. The thing I am confused with is that I am doing them in the late morning with my second urine of the day. Then I do another in the afternoon. My morning ones are darker than the afternoon ones. Why is it doing that? Normally I get my darker ones in the afternoon. I am holding my pee and watching my water intake so I know I am doing everything right. I am just confused. Here is a pic of my opks.
These are just the morning ones because the afternoon ones are very light.
