How accurate is Clearblue® Advanced Digital Ovulation Test? A laboratory test has shown the test to be over 99% accurate in detecting the LH surge (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.

The Clearblue Advanced Digital Ovulation Test (Prueba de Ovulacion Advanced Digital Clearblue) typically identifies 4 or more fertile days leading up to, and including the day of ovulation, at least twice as many as any other ovulation test.

The ovulation stick shows a clear smiley face on the digital display when your LH surge has been detected, so you know that today and tomorrow are your best 2 days when you're trying for a baby.

If conception is your goal, try to have sex with your partner a few times during this period to maximize your chances of getting pregnant. Even though you can still technically get pregnant anytime during the month, your highest chances of conceiving will be in these two to three days following your positive OPK test.

You are most likely to conceive during the 5 days before ovulation, along with the day you ovulate. Sperm can live up to 5 days inside your body, so if you have sex up to 5 days before your egg is released, you can get pregnant. After ovulation, your egg can only live for 12 to 24 hours.

Once you've taken several tests, you should be able to identify a spike in your levels of LH. For most women, this surge in LH is a sign that ovulation should occur within the next 24-36 hours. Together with your partner, you can use this information to plan intercourse on the days that you are the most fertile.

OPK's. (This is the best test for IUI timing.) Ovulation within 36 hours of a “smiley face” is a positive result (LH detected). This means you will have 1 to 2 fertile days.

Unfortunately, peak fertility only refers to two days - the day you ovulate, and the day before that. You're 30% more likely to get pregnant during peak fertility, so it's worth it to figure out how to identify your peak fertility days. Luckily, there are several ways to do just that.

This is because sperm can live for around 5 days inside a woman's body, so if you've had sex in the days before ovulation, the sperm can 'wait' for the egg to be released. These days before and just after the egg is released is often called the 'fertile window'.

There is a high chance of becoming pregnant if a person has sex within 12–24 hours after ovulation. A person can conceive at any time, but especially if they have sex from 5 days before until 1 day after ovulation. Ovulation occurs when one of the ovaries releases a mature egg.

You can assume you're fertile on the day of a positive E1G reading, and for about 5 days after. Many women also find other methods like basal body temperature tracking and cervical mucus monitoring helpful in predicting ovulation to identify the fertile window.
