By definition, ovulation is the process of an ovary releasing an egg from the follicle - permitting the egg to float down the fallopian tubes. Directly prior to ovulation, a dramatic hormonal change takes place - the LH Surge. LH (or Luteinizing Hormone) is the hormone that actually facilitates ovulation: it causes the egg to separate from the ovarian surface. Ovulation predictor tests function by detecting this LH Surge, thus alerting the woman that ovulation is imminent. See similar questions...

Most doctors will do an intra-uterine insemination (IUI) the day after the LH surge, or about 36 hours after it is detected. With a vaginal insemination, or an intra-cervical insemination (ICI) in someone with good fertile mucus, the day of the surge may be preferable. Many doctors are now doing two inseminations per cycle. Check the IUI FAQ. See similar questions...

It is possible to miss the surge. If you have a test line that is fairly dark one day then very light the next, you may have missed the actual surge.

Another possibility is that you didn't hold your urine long enough (resulting in a diluted sample). See similar questions...
