A number of possibilities, but it would be wise to check with your doctor, especially if your periods are normally regular.

Maybe try a pregnancy test as a positive pregnancy can show up with an ovulation test.

Be sure the test line is as dark or darker than the control line. Seeing a line does not necessarily mean positive and even a positive does not mean you are ovulating, only that your body is preparing to ovulate.

Could be hormones are such that the lining of your uterus is not preparing for a possible pregnancy and hence there is no period.

If you don't have a period when it is due next, visit your doctor and see if they might want to do some testing.
