Can LH Tests Be Wrong?

Do LH levels fluctuate?

It is normal for LH values to fluctuate throughout the cycle.

If you have very low values and don’t see a midcycle surge, you may not be ovulating.

It may be related to a pituitary disorder, anorexia, malnutrition, or stress.

Why are my ovulation test always negative?

A negative LH-test does not mean that you’re not fertile, or that ovulation will not occur. This only means that no LH surge has been detected at the time you tested, so it is encouraged to keep testing. You may need to test more often, 2-3 times a day to catch the surge.

Why am I not ovulating but having regular periods?

During ovulation, the ovary releases an egg, or oocyte. It’s not uncommon for a woman in her prime conception years to experience an anovulatory cycle occasionally. In fact, you may have experienced one and not even noticed. That’s because when a woman experiences anovulation, she may still seem to menstruate normally.

Why do I keep getting high fertility but no peak?

Occasionally some women have an LH surge that is too low for the test to detect, or they do not ovulate during a cycle and in this case they may see lots of High Fertility days but no Peak Fertility. This is not unusual and may happen in approximately 8% of cycles.

How accurate are LH tests?

Used correctly, the major-brand OPKs are more than 97 percent effective in detecting an LH surge, which is used as a marker for ovulation.

Can I have a negative ovulation test but still ovulate?

What time of day is LH highest?

How long should I hold my pee before taking an ovulation test?

Keep in mind that liquid can dilute the amount of luteinizing hormone (LH) in your urine. If this happens, it can appear as if you’re not ovulating when you are. So limit your intake of fluids about 2 hours before testing. It also helps not to urinate 1 to 2 hours before testing.

Can you still get pregnant with a low LH surge?

If your LH levels are low, you may not be getting your period. Because LH triggers ovulation, low levels of LH can prevent ovulation, and thus pregnancy.

What if no LH surge is detected?

If you test your urine every day during your mid-cycle and do not detect an LH surge, you may not be ovulating. Likewise, if your cycle is irregular, it may be more difficult to determine when you are ovulating, making it harder to plan conception.
