If I detect an LH surge, does that mean I am experiencing my most fertile days?

Yes. A surge in a woman's LH indicates that ovulation (the release of the egg) should occur 24-36 hours later. A woman is most fertile the day before, and the first day of ovulation. Therefore, if an LH surge is detected that means that the greatest likelihood of conception will occur throughout the next 24 hours.
