Understanding Ovulation
What is ovulation?
Ovulation is when a mature egg is released from the ovary. This typically happens once per menstrual cycle, about 14 days before your next period begins.
When is the fertile window?
The fertile window includes the 5 days before ovulation and the day of ovulation itself. Sperm can live for up to 5 days inside the female reproductive tract.
Signs of ovulation:
- Change in cervical mucus (clear and stretchy)
- Slight increase in basal body temperature
- Mild pelvic or abdominal pain (mittelschmerz)
- Breast tenderness
- Increased sex drive
Disclaimer: This calculator provides estimates based on average cycle data. For accurate fertility tracking, consult with a healthcare provider and consider additional methods like ovulation predictor kits or basal body temperature tracking.
