The Daily Digital Ovulation Test's unique technology helps you easily find the time you are most able to become pregnant by: Detecting the Luteinizing Hormone (LH) levels, which are always present in your urine. LH levels fluctuate daily and vary from woman to woman. Establishing your own personal LH baseline by determining an average of your LH level early in your cycle, on days 5, 6 and 7. The LH level increases just before your most fertile time of the month.
Detecting an increase or "surge" in your LH level, which triggers ovulation (the release of an egg from your ovary). You should have intercourse at any time during the next 24-36 hours after your LH surge is detected to maximize your chances of becoming pregnant. After the LH surge is detected, the next 2 days are the most fertile days of your cycle.
