This is my first month using the clearblue digital opk, also the first month my dh and I have been serious about ttc. My cycle is a little crazy I go two months of 30 days and then my third month is usually 45. I am in a 30 day cycle now. I started testing early and went from low to peak (solid smiley) on cd 10. I continued testing and now I am cd 19 and getting blinky smiley?? My cm is definitely feeling like getting ready to ovulate but now I am confused....
