Do you agree with me that CD 15 (today) 
((could actually really be cd 14 I didn't know if I was supposed to count drops of blood in cm as cd1, before the full flow began))  is it the darkest??
 Last month I O'd on cd 15  (for certain it was cd15 no spotting before af) once I took the smiley face test it was solid but this month the smiley face wasn't there but the red lines are telling me differently ... 
You think tomorrow it will be solid??
