Evidence shows that this time of increased fertility usually spans 6 days, starting approximately 5 days prior to ovulation and ending on the day of ovulation itself. The 6-day fertile period is affected by: The lifespan of the egg, which is up to 24 hours after ovulation.
It accurately monitors levels of LH and E3G to typically identify up to 6 days of high and peak fertility per cycle. This makes the Clearblue Fertility Monitor/Clearblue Advanced Fertility Monitor the most advanced home methods of maximising the chance of conception.
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.
There are only a few days per cycle when a woman is fertile and can conceive. Evidence shows that this time of increased fertility usually spans 6 days, starting approximately 5 days prior to ovulation and ending on the day of ovulation itself.
In that case, there's a good possibility that live sperm will still be active in your body and able to fertilize the egg released during ovulation. High fertility lasts from five days before ovulation until the beginning of peak fertility.
Flashing smiley – High Fertility
If the user has intercourse today she will increase her chance of getting pregnant, but she must also test again the following day.
For most women, the Clearblue Fertility Monitor will identify between 1 and 5 days of high fertility before they reach their peak fertility status.
It's possible for the holder to change from Low to Peak without displaying High Fertility. This can happen if your estrogen level isn't high enough to be detected by the test, if your hormone changes occur on the same day, if a test is inadvertently missed, or if testing begins too late in your cycle.
Even if you haven't ovulated yet, you could still get pregnant from having sex during high fertility. That's why this time is also called your fertility window, because there's not just one day when pregnancy can occur — there are a range of days depending on the egg and sperm.
Ultimately, your chances of getting pregnant on each day leading up to and after ovulation are roughly: 27%: 3 days before (high fertility) 33%: 2 days before (high fertility) 41%: 1 day before (peak fertility)
The days during each cycle when you are most fertile, and therefore most likely to get pregnant from unprotected sex, are the day of ovulation and the day before – these are the two days of peak fertility.
Ovulation within 36 hours of a "smiley face" is a positive result (LH detected). This means you will have 1 to 2 fertile days. One kit can be used for more than 1 cycle.
Ovulation is considered to occur 28-36 hours after the beginning of the LH rise or 8-20 hours after the LH peak.
Most women will have 2 days of flashing smiley faces before the peak fertility is reached. Peak fertility is a smiley face. Once peak is reached, the meter shows the result for 48 hours, which is a reminder to you that your best chance to conceive is the next 48 hours.
Pregnancy is technically only possible if you have sex during the five days before ovulation or on the day of ovulation. But the most fertile days are the three days leading up to and including ovulation. Having sex during this time gives you the best chance of getting pregnant.
That being said, it is possible to miss an LH surge as they can be very short — sometimes they only last 12 hours. To ensure you catch your LH surge, we recommend beginning testing early in your cycle and testing multiple times per day (but more on this later!).
Clearblue Pregnancy tests are over 99% accurate from the day of the expected period and most Clearblue pregnancy tests can be used up to 5 days before a missed period.
Intriguing evidence10 suggests that in conception cycles, ovulation always occurs within 24 hours of peak serum LH, but in non-conception cycles, this is pushed out to up to 48 hours later.
Myth 5: Ovulation strips work for everyone
It usually occurs between midnight and early morning. This marks the most fertile period of the menstrual cycle.
The greatest chance of conception occurs when there is intercourse 1 to 2 days prior to the actual ovulation,” says Dr. Witt. The two days leading to ovulation are known as peak fertility days, a period when intercourse would most likely lead to pregnancy.
Fast-swimming sperm can reach the egg in a half an hour, while others may take days. The sperm can live up to 48-72 hours. Only a few hundred will even come close to the egg because of the many natural barriers that exist in a woman's body.
For the most accurate result, health care providers suggest testing twice a day, 10 hours or more apart, for a few days prior to ovulation. Log your ovulation test results, and Flo will use them to make even more accurate predictions.
Once the sperm enters the reproductive system, it can take about 30-45 minutes to reach the egg. For this, it is important to have a healthy sperm which has the right kind of motility to reach the egg and fertilize it. Once inside the body of a woman, a healthy sperm can live up to 2-5 days.
As you get close to ovulation, your cervical mucus will become copious, clear and slippery—like egg whites. It stretches between your fingers. Once your discharge becomes scant and sticky again, ovulation is over.
