How to Calculate Ovulation with a 37-Day Cycle

In a typical 28-day cycle, ovulation usually happens around day 14. However, with a 37-day cycle, ovulation typically occurs around day 23. This is calculated by subtracting 14 days from the expected start of your next period. Use our ovulation estimator to calculate your fertile window based on your last period.

The fertile window includes the five days leading up to ovulation and the day of ovulation itself. This is because sperm can survive for up to five days in the female reproductive tract, waiting for the egg to be released. Therefore, having intercourse during this window maximizes your chances of conception.

Signs of Ovulation

Even with a longer cycle, the signs of ovulation remain the same:

  • Changes in Cervical Mucus: Clear, slippery, and stretchy, resembling egg white.
  • Increased Basal Body Temperature (BBT): A slight rise in temperature.
  • Ovulation Pain (Mittelschmerz): Some women experience mild pain or cramping on one side of their lower abdomen.
  • Increased Libido: A heightened sexual desire.

While the calculations above provide a general guideline, individual variations can occur. Our comprehensive Pregnancy Calculator & Ovulation Estimator tool offers a personalized timeline based on your unique cycle length. Here's how it helps:
