the peak day is the one when the ovulation line is darker than the other which appears anyway!...so from what i see you dont have a positive yet...maybe you did ovulate but before the tests you drunk too much liquid so it couldnt show anything since the urine sample wasnt good...you must hold your pee and dont drink too much liquid for at least 4 hours!
also its better around ovulation time (if you have a regular cycle) to have one test in the am -note:NOT THE FIRST URINE OF THE DAY when you do the ovulation test-and one in the pm before 8 o'clock...
but as i did in another thread i would like to ask you also, do you have regular cycles???do you have pcos?just to inform you people with pcos and irregular cycles tend to get many false positives since the ovulation tests just show the surge of the hormone which is required to make the ovulation happen NOT if it actually happened ...sometimes we may not ovulate and still get our period...(the egg doesnt break so it just starts the phase the second phase of our cycle without ovulation...until the arrival of AF)
doctors say that its actually normal for the ovulation not to happen for some cycles in every woman's life even to the ones that have regular cycles(since stress can effect the ovulation-in fact stress effects the hormones that are required to make it happen, weight issues, bad eggs etc)
in my opinion all you see in nature is the survival of the strongest so i'm sure that happens with our eggs as well!its just the nature doing its work and that might actually saves many women from pregnancies that would turn into miscarriages
anyway, the ovulation if it truly takes place can only be confirmed via blood test, u/s and temping chart.but then again about temping to be accurate you must have at least a 5-6 hour sleep,no insomnia...and temp at the same hour each day!not at 6 o'clock in the weekdays and 11 at weekends!
