CD 14 still negative opk!?

Laura

This is my 3rd cycle ttc and 3rd cycle off bc. Only my 2nd month using ovulation sticks. 2 months ago I got my positive smiley face on 13dpo! This month still nothing!!! I have had a 28 day cycle and a 30 day cycle since off birth control. When did you get your positive opk? How common is it to have an annovulatory cycle? Thanks all! This is whole telling your self not to stress is basically useless :)
