An : An ovarian cyst should not cause a false negative on a hpt, however there are other causes. These includs: testing too early error when performing the test not reading the result when directed, i.e. Waiting too long to read the result my advice would be to repeat the test if your period does not start in another week or so, or you can have one done in your doctor's office sooner. Good luck.
