We often spend our younger years evading our monthly cycles, but once we decide to conceive, everything changes. Suddenly, keeping track of Aunt Flo’s arrival becomes crucial for identifying our most fertile days. Ovulation typically happens about 12-14 days after your last period, right before the next one. This fertility window is surprisingly brief—averaging just 3-5 days.
While many women with regular cycles (roughly every 28 days, give or take a week) can estimate when they will ovulate, they might still miss the narrow window. That’s where ovulation tests and predictor kits come into play. These tests usually analyze a urine sample to detect a hormone called LH (luteinizing hormone), which surges right before ovulation.
How do ovulation tests function?
“Every month, at the beginning of your cycle (day 1 is counted from the first day of your full flow), you have a group of resting ‘follicles’ in your ovaries, which are tiny sacs containing immature eggs,” shares Dr. Lisa Grant, a reproductive endocrinologist at the Coastal Fertility Center. “For those with regular cycles, the brain releases FSH, or Follicle Stimulating Hormone, which prompts one of these follicles to grow and mature the egg.” As the follicle develops, it produces estrogen, signaling the brain to halt FSH production and begin producing LH—the hormone that ovulation kits look for in urine.
What types of ovulation tests are available?
Dr. Emily Bennett, a fertility expert and gynecologist, favors the traditional kits that display two lines over the more modern digital options. “The lines help women notice subtle changes as they occur,” she explains. “With digital kits, users might miss their peak, as they only show high or low readings.” However, some women appreciate digital kits for tracking and charting more detailed information about their cycles.
