Ovulation Tracking in Seoul, Korea


Your period usually starts about 14 days after ovulation. With regular cycles, ovulation is roughly 14 days before your next expected period. For accuracy, combine three methods: follicle ultrasound (ovulation usually happens near 2 cm), urine ovulation test kits, and your last 3–6 months of cycle dates.

The key rule

If you ovulate, your period comes about 14 days later. If you do not ovulate, your period does not come.

Three methods together

  1. Follicle ultrasound – measures follicle size; ovulation usually occurs around 2 cm
  2. Urine ovulation tests – sold at Korean pharmacies
  3. Cycle history – estimate from your last 3–6 months

If your cycle is regular

Subtract 14 days from your next expected period. For example, if your period is due on 30 August, ovulation is expected around 16 August. Start ovulation tests the day before. A test is positive when the test line is as dark as or darker than the control line, not simply darker than yesterday. You can photograph confusing tests and bring them in.

If your cycle is irregular

Book an ultrasound near your likely ovulation window, then repeat ultrasounds or use ovulation tests once ovulation is close. Consider hormone testing.
