If your cycle is irregular or if you rarely or never get a menstrual cycle, then you likely have a problem with ovulation. If you test your urine every day during your mid-cycle and do not detect an LH surge, you also may not be ovulating.

Could no LH surge mean pregnancy?

No, LH surge does not remain elevated once pregnant. In fact, LH levels are really low during pregnancy (< 1.5 IU/L), and thus not active on end organs and tissues.

Can LH surge be missed?

If you start testing too late into your cycle, you may miss the LH surge and won't get a positive result that month. Ovulation predictor kits can be expensive, and the cost can add up if you use several of them throughout a cycle, or through multiple cycles.

Why am I not getting a positive ovulation test?

Another possible reason you won't get a positive result is you're not ovulating. It's not abnormal to have one off cycle, once in a while. However, if you don't get a positive result after a few months, or if your cycles are irregular, talk to your doctor.

How can I trigger my LH surge?

When estradiol levels attain a persistently high critical concentration in the late follicular phase, they induce the LH surge. Following ovulation, estradiol concentrations dip temporarily but are revived by corpus luteum activity.

What does a very faint line on an ovulation test mean?

Can you get pregnant if ovulation test is negative?

Can you have a negative ovulation test and still ovulate?

What time of day is LH surge?

The LH surge triggers the egg to fully mature and to be released from the follicle. A study of 155 cycles from 35 women demonstrated that the onset of the LH surge primarily occurs between midnight and early morning (37% between 00:00 and 04:00, 48% between 04:00 and 08:00).

How do I know if I skipped ovulation?

You can suspect the lack of ovulation if: your periods are irregular and can be late for up to 10 days or more. (In very rare cases, regular cycles can be anovulatory, too.) you have short cycles (less than 21 days).

Can you miss LH surge testing twice a day?

Sometimes, the peak time of luteinizing hormone is short and lasts only a couple of hours. To make sure you don't miss the surge of the hormone, it may be helpful to take the test twice a day. If the peak time is long (more than 24 hours), one test is enough to indicate an increased level of the hormone.

Can Estrogen rise but no LH surge?

Anovulatory cycles with fluctuating estrogen levels: In the above cycle, estrogen levels (green line) will start to rise, but they never get high enough to induce a luteinizing hormone (LH) surge and trigger ovulation. However, we see somewhat “regular” drops in estrogen, which occur after failed ovulation attempts.

Why are my LH tests 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.

How accurate are LH strips?

Ovulation test strips can do an excellent job of letting you know when you're most fertile. In fact, studies suggest they can detect ovulation up to 97 percent of the time, making them the most accurate option out there.

How accurate are ovulation strips?

While ovulation test strips can determine your most fertile days, they're not 100 percent accurate. But don't worry too much — they can have an accuracy rate up to 99 percent, depending on your menstrual cycle. To test ovulation, you can urinate on the test stick, or urinate in a cup and place the stick in the urine.

Can LH surge vary month to month?

In women with regular menstrual cycles, the LH surge usually occurs between cycle days 12 to 16. The day of the LH surge may vary from cycle to cycle in all women, just as their cycle interval may vary. In women with shorter or longer cycle lengths, the LH surge may occur before day 12 or after day 16.

What time of day is LH highest?

Ovulation is related in time to the onset of the LH surge, and occurs 40–45 h following the onset of this surge as detected in blood. The commonest time for the LH surge (as detected in blood) to commence is between 05:00 and 09:00.

When are you at your most fertile?

You're most fertile at the time of ovulation (when an egg is released from your ovaries), which usually occurs 12 to 14 days before your next period starts. This is the time of the month when you're most likely to get pregnant. It's unlikely that you'll get pregnant just after your period, although it can happen.

How do I know if I am fertile enough to get pregnant?

If your menstrual cycle lasts 28 days and your period arrives like clockwork, it's likely that you'll ovulate on day 14. That's halfway through your cycle. Your fertile window begins on day 10. You're more likely to get pregnant if you have sex at least every other day between days 10 and 14 of a 28-day cycle.

Women with LH deficiency should receive estrogen replacement therapy. If they desire fertility, they should receive a referral to reproductive endocrinology. Patients must be knowledgable about the side effects of hormone therapy.
