Ovulation & Fertile Window

Ovulation is the release of a mature egg from the ovary, typically occurring about 14 days before the start of your next period. The fertile window spans approximately 5 days before and 1 day after ovulation, when the chance of conception is highest.

Signs of Ovulation

  • Slight rise in basal body temperature (0.2-0.5 degrees)
  • Changes in cervical mucus (clear, stretchy)
  • Mild lower abdominal pain (mittelschmerz)
  • Increased breast sensitivity
