I dont know if the picture really shows how dark these are very well, but can anyone tell me if they had OPKs this dark on CD 5 and 6?? This is seems wrong to me.... Ive been doing this for a while and usually around now they are clear or VERY light... I have a very standard 29 day cycle where I always ovulate between the 15-17 day... what could be going on? Any ideas? And if you have had them like this please show me! Thanks in advance!
