The <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says I'm to ovulate tomorrow, but I have no symptoms. I usually get sore boobs, back pain, higher sex drive.....you know. I also take clear blue OPK to check.This time I have only one left from the last package I bought, which I was going to use when I started those symptoms. I am on CD14. My cycles are 28 to 29 days.... i ususally ovulate around day 16 to 17, but I get symptoms prior to that..... does it mean I am not ovulating this month. Can any one give me some advise. thank you all.
