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.

Typically identifies 4 or more fertile days. 1 By measuring these two hormones, the Clearblue Advanced Digital Ovulation Test accurately detects the timing of a wider fertile period of typically 4 days, 2 more than other ovulation tests.

The results can be read at any time between 3 and 10 minutes after performing the test. Discard the test after 10 minutes. READING THE RESULTS Look at the Result Window and compare the Surge Line to the Reference Line. The line next to the arrow is the 'Surge Line' which indicates the level of LH in your urine.

An error has occurred during testing. It may be that: You have done the test before inserting the test stick into the holder. The absorbent tip was not kept pointing downwards or the test was not laid flat after testing.

Occasionally some women have an LH surge that is too low for the test to detect or they do not ovulate during a cycle. This is not unusual and may happen in approximately 8% of cycles1.

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.

When your LH surge is first detected, the test will display a static smiley face and this will continue to be displayed constantly for 48 hours, indicating your 2 most fertile days.

During the average woman's menstrual cycle there are six days when intercourse can result in pregnancy; this “fertile window” comprises the five days before ovulation and the day of ovulation itself. Just as the day of ovulation varies from cycle to cycle so does the timing of the six fertile days.

Ovulation happens about 14 days before your period starts. If your average menstrual cycle is 28 days, you ovulate around day 14, and your most fertile days are days 12, 13 and 14. If your average menstrual cycle is 35 days ovulation happens around day 21 and your most fertile days are days 19,20 and 21.

Ovulation is when an egg is released from an ovary. Your ovulation period lasts for 12 to 48 hours. Typically, this takes place mid-cycle, but the exact timing is different for each menstruating person.

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 fertilized for up to 24 hours after ovulation. If it isn't fertilized the lining of the womb is shed (the egg is lost with it) and your period begins.
