Most people will ovulate 12-48 hours after the LH surge is detected, most common is 36 hours after the actual surge. One should get a bit more notice, 24-48 hours, by testing in the afternoon.

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.

Most doctors will do an intra-uterine insemination (IUI) the day after the LH surge, or about 36 hours after it is detected. With a vaginal insemination, or an intra-cervical insemination (ICI) in someone with good fertile mucus, the day of the surge may be preferable. Many doctors are now doing two inseminations per cycle. Check the IUI FAQ.

Most people will ovulate between 12-48 hours after detecting their surge with 24 hour being very typical.

It is recommended to have intercourse the day of the LH surge and the two days following. Most women conceive from intercourse prior to ovulation. There can be special circumstances where you would be advised to not have intercourse all three days. Please consult your doctor if your partner has a low or borderline sperm count.

By definition, ovulation is the process of an ovary releasing an egg from the follicle - permitting the egg to float down the fallopian tubes. Directly prior to ovulation, a dramatic hormonal change takes place - the LH Surge. LH (or Luteinizing Hormone) is the hormone that actually facilitates ovulation: it causes the egg to separate from the ovarian surface. Ovulation predictor tests function by detecting this LH Surge, thus alerting the woman that ovulation is imminent.

It's best to have intercourse the day of the LH surge and the two days after. Also consider "insurance" sex for one more day in case you ovulate late. Perfect timing would be to have had intercourse the day before the LH surge as well, but that can be hard to predict for those with an irregular cycle. If you don't know when you might ovulate, having sex every other day from cycle day 10 through a positive OPK.

The correct cycle starting date may have been miscalculated, or one of the above factors may have influenced test results. Each test cassette has built in quality controls which make a defective test highly unlikely. Recalculate your cycle test start date and repeat the testing in the next menstrual cycle. If the LH surge is still not detected, you may wish to consult a physician. An insufficient amount of urine has been dropped in the sample well on the cassette.

For women who have regular cycles, ovulating during your period is highly unlikely. Some women have very irregular cycles, maybe coming once every 3 months or 2-3 times in one month, and these women can have the odd occurrence of ovulating during a period or what is believed to be a period. Still, the chance of ovulating during a period is unlikely. But because sperm can live in the body for 3-5 days, pregnancy could occur from intercourse that takes place during a period.

You do not need to continue testing once the LH surge has been identified. You may save any unused tests for future testing, however be certain not to open the sealed pouch of any test prior to immediate use to avoid possible contamination the sensitive testing area membrane.

No. Each test result should be read independently of any other test. When the LH surge occurs, that particular day’s test will show positive results. No. All urine based LH tests are intended to be used with each test independent from any other test. Once a positive test is obtained testing should be stopped. the LH surge has begun. Test results, including the color or intensity of test or control lines, cannot be compared or correlated one test to another.

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).

The answer to this is determined by how many days are in your cycle. For example, if you have a 21 day cycle ( from the beginning of one period to the beginning of another) and you bleed for 7 days, then yes, you could ovulate right after your period. This is because we know ovulation can occur 12-16 days before your next period begins, and this would put you ovulating at days 6-10 of your cycle.

A woman cannot ovulate more than once during each cycle, therefore she cannot get pregnant more than once during a cycle. Multiple ovulation can occur and is when two or more eggs are released in a single cycle. Both eggs are released during one 24 hour period and are responsible for the birth of fraternal twins.

Since a woman releases an egg 12-16 days before her expected period, it is possible for women to get pregnant without having periods. Women who are not menstruating due to a certain condition (i.e.…low body weight, breastfeeding, perimenopause) risk the chance of ovulating at any point. For those who want to conceive, the lack of periods could make it more difficult to know the timing of ovulation if you are not charting temperature and cervical fluid changes.

No! The day of ovulation can vary among women as well as within each individual woman. However, once a woman ovulates, the time between ovulation and her menstruation is very consistent, almost always between 12 and 16 days. Within most individual women, this length of time generally doesn't change by more than a day or two. In other words, if there is going to be variation in the cycle, it is the first preovulatory phase that may vary.

Ovulation usually resumes when hCG levels decrease below 100 IU/l. Therefore it is not unusual to diagnose ovulation when an ectopic pregnancy is in state of resolution following expectant or medical treatment.

Ovulation can take place even if you do not notice the “stretchy egg-white” fluid that we assume accompanies ovulation. Every woman can experience her own type of cervical fluid, and not all are the same. Ovulation is assumed to take place on the day a woman has the most amount of wet fluid.
