Once an LH surge is documented, it is no longer necessary to continue testing during that cycle. Occasionally, ovulation may not occur in a cycle despite an LH surge.

It's possible, but highly unlikely. You'd have to have a very short menstrual cycle. This would bring the time of ovulation closer to the time when you are bleeding, especially if your period tends to last a long time.

Ovulation prediction tests such as First Response Ovulation Test are helpful as well. One word of caution: ovulation can occur within a two-day window after a positive LH surge (the hormone an ovulation test measures), so have intercourse once per day for two days after a positive ovulation test.

Ovulation happens when an ovary releases an egg in preparation for pregnancy. In some menstrual cycles, an egg does not mature, and a woman does not ovulate. This is known as anovulation. Anovulation may cause irregular menstrual cycles or no periods at all.

Levels of LH are low for most of the monthly menstrual cycle. However, around the middle of the cycle, when the developing egg reaches a certain size, LH levels surge to become very high. A woman is most fertile around this time.

Ovulation that happens regularly after CD 21 is not considered normal. That does not mean you cannot get pregnant with late ovulation. Women get pregnant all the time even when they ovulate late. But your chances of getting pregnant are decreased significantly when you ovulate late.

Irregular periods and ovulation. It's possible to ovulate without later bleeding like a period. This often occurs because of previous uterine scarring or certain hormonal medications. It's also possible to have menstrual-like bleeding without ovulation.

Yes, it is very much possible to ovulate and get pregnant without your periods. This is most likely the case with women who face the problem of irregular periods.

When the body's levels of luteinizing hormone (LH) rise, it triggers the start of ovulation, and the most fertile period of the menstrual cycle occurs. Tracking the surge in luteinizing hormone levels can help people to plan intercourse and increase the chances of becoming pregnant.

When your LH surge test is positive, it's the perfect time to start having second daily sex to get pregnant. Some women can physically feel when they ovulate (a pain technically known as mittleshmertz meaning “middle pain” – aka middle of the menstrual cycle) but many women can't.

Why is the LH surge important? Your LH surge is important because it initiates the beginning of ovulation and your fertile period. If you're trying to get pregnant, this is the best time for you to begin having sex without a condom. Once the egg is released, it's only viable for about 24 hours.

Ovulation normally occurs 24 to 36 hours after the LH surge, which is why the LH surge is a good predictor of peak fertility. The egg can only be fertilised for up to 24 hours after ovulation.

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.

Implantation usually occurs 6–12 days following LH surge [11–14].

Not Ovulating Human conception requires an egg and sperm. If you're not ovulating, you won't be able to get pregnant. Anovulation is a common cause of female infertility and it can be triggered by many conditions. Most women who are experiencing ovulation problems have irregular periods.

The LH surge triggers ovulation, which is the start of a woman's fertile period. When an ovulation test result is positive, it means that LH levels are high, and ovulation should occur within the next 24 to 36 hours.

Within 24 to 36 hours of an LH surge, a mature egg will be released (or ovulated) for fertilization. An egg is available for fertilization for 12 to 24 hours after ovulation. It will disappear after 24 hours if it is not fertilized.
