Lh Surge

Lizzie asks…

Is it possible to ovulate three days after LH surge?

I had a positive LH surge on Friday and Saturday. It is now Tuesday and I am just now getting the cramping I usually get when I ovulate. Is it possible to ovulate so long after the LH surge?

Pregnancy Advisor’s answers:

Yes, usually it happens 24-48 hours after you LH surge, but it can happen 3 days after. Also, sometimes women cramp a little the day after they ovulate

Betty asks…

I tested for LH surge Monday the 17th, do you think I should still have intercourse today and tomorrow?

I know that sounds silly but we had sex sunday before I detected LH surge and then the 2 days after. Am I still fertile? Should we still be trying????
we did have sex the day before I detected surge, NOT the day of BUT the two days after that so I think im in good shape.. atleast I hope!

Pregnancy Advisor’s answers:

Okay i think this has to be the easiest 2 points ever on yahoo answers.okay you got a surge on the 17th? Why would you wait now to have sex? You should have done it the day of, the next day and the last day of the negative surge.right now your chances are super low.i hope i could help.

Donna asks…

Is it possible to ovulate and not detect an LH surge?

Ive been taking clomid and had a follow up ultrasound this past monday. The doctor detected two follicles that are just about to be released. He said I should ovulate sometime this week. I know the week isnt over yet, but still no LH surge….Any thoughts?

Pregnancy Advisor’s answers:

I mean it’s probably possible you may not be doing the tests right or maybe their faulty. But again wait the week out… And see! 🙂
Good Luck

Laura asks…

Once I test positive for a LH surge, when is the best time to have intercourse?

I tested positive for LH surge this morning. So would it be better to have intercourse tonight or tomorrow morning? I need a little help understanding the 24-36 hours the box says. Also, my hubby is 15 years older then me, so a sex-marathon is out of the question.

Pregnancy Advisor’s answers:

Luteinizing hormone in elevated quantities causes ovulation. During most of your menstrual cycle, only a small amount of LH is made. But in the middle of the cycle, LH briefly and dramatically surges to facilitate the release of the ovum from the ovary. This increase is called the “LH surge” and precedes ovulation. Conception is most likely to occur within thirty-six hours following the LH surge. If you are trying to conceive, then knowing when the surge of lh takes place will help you pinpoint when you have the highest chances of getting pregnant.

Q: How do I interpret OPK results? Are lh tests the same as hCG pregnancy tests?

Ovulation tests function differently than hCG tests. A positive result on an ovulation test (indicating an LH Surge) is indicated by a test band that is of equal or greater intensity (equal or darker) than the control band. A negative result for the LH Surge is indicated when the test band is of lesser intensity (lighter) than the control band or cannot be seen. With a pregnancy test, you are simply looking for the presence of a test line (not faintness or degree of intensity).

Q: What is the best time of day to take the ovulation test?

Unlike the pregnancy test kit, morning (first morning urine) is not the best time to collect samples for ovulation tests, as LH is synthesized in your body in the morning and will not appear in your urine until the afternoon. The ideal time to collect a urine sample is in the afternoon, though testing may safely take place from 10am to early evening.

Q: Should I take the test the same time every day?

Yes: To optimize accuracy of results, test at the same time each day. Reduce your liquid intake around 2 hours before testing as a diluted liquid sample can hinder detection of the lh surge.

Q: How long after my LH surge will ovulation take place?

Generally, ovulation will take place 12-48 hours after the LH surge is first detected (using afternoon urine samples), though 36 hours is considered to be the average length of time following the LH surge. Once you get a positive, you know you are at peak fertility. Timing intercourse will increase your odds of conception.

Q: When I get a positive result, when is the best time to have sex?

To increase the chance of conceiving, it is recommended to time intercourse the day of the LH surge as well as following three days after.

Q: Does the appearance of faint ‘test band’ indicate an LH surge?

A faint test line does not indicate a positive result for an LH surge. While the presence of a faint line on a pregnancy test may indicate a positive result, a faint line on an ovulation test, it is always negative.

Q: Does taking my basal body temperature tell me the same thing as an OPK?

Basal Body Temperature only tells of your LH surge after it is over. That is why the BBT method cannot predict the LH surge. Ovulation tests will tell you – with pinpoint accuracy – when your chances for conception are greatest.

Q: Can OPKs be used as contraception devices?

Ovulation tests are designed to help facilitate pregnancy. They are not recommended for contraception.

Q: Can clomid interfere with test results or cause false positives?

Clomid may cause a false positive result if you begin testing for ovulation too early in your menstrual cycle. Please consult with your doctor about how to use OPKs in conjunction with Clomid – or other fertility and prescription medications.

Q: Does a light test line and a dark control line indicate a positive result?

Ovulation tests are not the same as pregnancy tests – especially when it comes to interpreting results. The results are only positive if the test line is equal to or darker than the control line. Do not try to second guess an ovulation test. While a faint test line may indicate that the lh surge has started, it may also simply be the result of naturally low levels of LH that may be in your system normally throughout your cycle.

Q: I had a positive result yesterday and today. Does that mean there is something wrong?

Some women experience 2 and more rarely 3 days of an lh surge. Such results may indicate that your the tests detected the LH Surge on the way up (lh increase) and again on the way down again (lh surge decrease).

Q: What if I experience a BBT thermal shift but the ovulation tests failed to detect my LH Surge?

It is possible to miss the surge. If you have a test line that is fairly dark one day then very light the next, you may have missed the actual surge. If your thermal shift occurs, you probably ovulated. It may be a good idea to test twice a day when you feel that you are close to ovulating. Another possibility is that you didn’t hold your urine long enough (resulting in a diluted sample).

Other Notes from the Manufacturer

1) Should I restrict my diet before taking the test?
No, diet will not affect the test results.

2) Does alcohol, aspirin, or any other common drug affect the test?
