Question 1

When do I ovulate?

Accepted Answer

Ovulation typically occurs about 14 days before your next period starts. For a 28-day cycle, that's around day 14. For a 30-day cycle, it's around day 16. Ovulation day can vary based on stress, sleep, and other factors.

Question 2

How long is the fertile window?

Accepted Answer

The fertile window is about 6 days — the 5 days before ovulation plus ovulation day itself. Sperm can survive up to 5 days in the reproductive tract, while the egg only lives 12-24 hours after ovulation.

Question 3

What are signs of ovulation?

Accepted Answer

Common signs include clear, stretchy cervical mucus (like egg whites), a slight rise in basal body temperature (0.5-1°F), mild pelvic pain (mittelschmerz), increased libido, and breast tenderness.

Question 4

Can I get pregnant outside my fertile window?

Accepted Answer

Pregnancy outside the fertile window is very unlikely but not impossible, especially with irregular cycles. For reliable contraception, use barrier methods or discuss options with your healthcare provider.

Question 5

Is the ovulation calculator accurate?

Accepted Answer

Calendar-based ovulation prediction is accurate for regular cycles but can be off by 3-5 days for irregular cycles. For maximum accuracy, track ovulation signs (BBT, cervical mucus, ovulation tests) or use an AI-based tool like Cyra that learns YOUR pattern.

Question 6

How do I find my fertile days?

Accepted Answer

Enter your last period date and average cycle length above. This calculator predicts your ovulation day and shows your 6-day fertile window across 3 months. For personalized predictions based on YOUR body, try the Cyra app.
