I have a 28/29 day cycle and I am using the new clearblue dual opks this month. I am currently on day 16 and not had a peak yet. I have been on high fertility since Friday (day 12) I have one stick left and rang the helpline this morning and was advised to do the test tomorrow but don't bother doing any more this month as I have probably missed my surge?? What do you all think? This is my first month of using opks! Feeling very frustrated!
