Q: Is it possible that my Ovulation Preditor Kit (OPK) was positive without ovulation?

A: It is possible to have a positive OPK without ovulating. The OPK does not test for ovulation, but for the LH hormone, which usually precedes ovulation and which stimulates the egg to ovulate. A positive OPK without ovulation can happen under the following circumstances:

  1. LUFS (luteinized unruptured follicle sydrome) where there is a surge in LH but no egg is released.
  2. Premature ovarian failure
  3. Menopause
