I’m so annoyed.. iv for some reason started having 15-20 day cycles for the last few months so I literally get a period every two weeks and it makes it so hard to track ovulation. From the day AF finished I started tracking with CB advanced, FR, and some cheapy brand and I just can’t seem to get a positive from the day AF finishes to the day of next AF. 😡 All of them said negative except CB said “high fertility” flashing face for every day of my cycle in between AF. Even today when AF arrived still a flashing face. Mean while all the others have been negative. Iv been taking Vitex, vitamins B6 & B12, prenatal. No matter what I do I just don’t think I’m ovulating. Can anyone shed some lights, suggestions, or experience??
