I'm on my cycle day 16 and I have taken ovulation tests for 9 days now and they were all negative, even after i had eggwhite discharge 3 days ago. I have been using clear blue digital ovulation tests and have not even had the hint of any results no matter what time of the day I am testing. Is there something I'm doing wrong or is there a problem? My husband and I have had sex everyday for the past 8 days and every other day before that since the start of my cycle in hopes of not missing my window.
