I've been using Clear Blue Digitals and have been so frustrated with the amount of money spent and testing errors despite following the directions to a T. I just went out and bought some cheaper strips. This was taken at 2pm. I know I don't have any others to compare to but just wondering what everyone thinks? I'm on CD 21, have had about a 30 day cycle after miscarrying in December. According to the app I should be ovulating any time now. Thanks in advance!
