You asked: Can a positive ovulation test be wrong?

Since ovulation kits test for LH, they may yield positive results all the time or on several days. These positive results are false-positives—they don’t mean you’re ovulating. They can signal that your body is trying to ovulate, but they can’t confirm that ovulation happened.

What can cause a false positive LH surge?

Women who have polycystic ovary syndrome may experience false small peaks of LH. Those who have recently hit menopause or were recently pregnant can have false positives, too. The American Pregnancy Association also notes that some prescription drugs can also affect your results.

How accurate is a positive ovulation test?

Can LH surge be wrong?

Why is my ovulation test always positive?

A positive result indicates the presence of a high amount of LH, or your LH surge. The amount of LH in your body will begin to decrease after ovulation, so you’ll only get a positive result during that crucial fertile period.

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.

Is it possible to ovulate and not have LH surge?

No, it’s not possible to ovulate without a LH surge. That’s because LH is a hormone released by the pituitary gland and plays a fundamental role in the egg’s growth and maturation; a large burst of LH induces the release of a mature egg (9).

Does two lines on an ovulation test mean im pregnant?

Unlike a pregnancy test, two lines alone is not a positive result since your body makes LH at low levels throughout your cycle. A result is only positive if the test line (T) is as dark or darker than the control line (C) line.

Can you get pregnant even if ovulation test negative?

Can I get pregnant if the ovulation test is negative? If the test is performed correctly and the LH surge has not yet occurred, you cannot get pregnant.

What time of day does LH surge happen?

The LH surge begins around 36 hours before ovulation. Once the egg is released, it survives for about 24 hours, after which time the fertile window is over. Because the period of fertility is so short, it is important to keep track of it when trying to conceive, and noting the timing of the LH surge can help.

Can you have more than 1 LH surge in a cycle?

This can be more likely to happen in times of stress, illness, or hormonal change, but these are not necessarily the only times. If you have ever received two peak readings or a second LH surge in one cycle just a couple of days apart – you may have experienced multiple follicular stimulation.

How do you confirm ovulation?

To confirm ovulation, serum progesterone or its metabolite in urine, can be measured. A single serum progesterone level >3 ng/ml in mid‐luteal phase has been used to retrospectively detect ovulation.
