What if the LH surge is not detected?

There are several explanations if you cannot detect an LH surge. One possibility is that you may not have ovulated in the particular month. This may occur occasionally, and it is normal. Another possibility is that you missed your LH surge and that it either occurred before or after the test series. This might be due to an irregular cycle or you may have miscalculated your menstrual cycle. You might want to continue testing with another test kit or start testing earlier in the next month. Also make sure that the urine sample was reliably collected. Different times of the day and irregular liquid uptake may interfere with the result of the test. If you continue to get readings that do not correspond to the expected results, please consult your physician.
