I have been testing with an ovulation predictor kit since Thursday day 11 in my cycle (today being day 14) and I keep getting negatives. I am using the first morning urine since I cant hold for 4 hours during the day. I had EWCM yesterday so I assumed today would be a positive. If you have used them what do you think of them? I am going to judge my own body by the cm I guess.

If this isnt our month, I will try that! Thanks for sharing!
Testing first thing in the morning isn't going to give you the best results. I didn't usually ovulate until Day 21ish, but would sometimes have some CM that resembled EWCM a week or more before.
If you can, try to at least hold it for 2 hours in the middle of the day and test. Also, make sure you test the same time each day (I believe that's the rule for OPKs)
Definitely try testing later in the day- I never held my pee for 4 hours- there's no way!! I still got positives. I just tried to hold it for 1-2 hours if I could.
HTH! GL!
Is this your first month charting/using OPKs? Most women do not ovulate on the 15th day.
I used OPKs for over a year and would buy internet cheapies so I could test every morning with FMU. Once I got to CD 12 I would test twice a day, in the morning and at around 2pm so I wouldn't miss the surge.
