Frequently asked questions
- How accurate is this ovulation calculator?
- Cycle lengths vary, and ovulation can shift by several days due to stress, illness, or hormonal changes. Use this as a guide, not a certainty. Ovulation predictor kits give same-day confirmation.
- When is the best time to try to conceive?
- The 2–3 days just before ovulation are statistically the most fertile, as sperm can survive several days in the reproductive tract.
