Written by The Kalcule Team · Last updated 2022年9月21日
使用我们全面的排卵计算器计算您的排卵期和排卵日期。根据您的月经周期获得个性化预测，以帮助您计划怀孕或跟踪您的生殖健康。
为什么追踪排卵很重要
了解你的排卵周期对于家庭计划和生殖健康至关重要。无论你是在尝试怀孕还是在跟踪你的周期，知道你的生育窗口可以帮助你做出有关生殖健康的明智决定。
如何使用排卵计算器
- 1选择您上一次月经周期的第一天
- 2请选择您的平均周期长度（通常为26-30天）
- 3获取您预测的排卵日期和易孕期窗口
- 4查看带有颜色编码日期的生育力日历
追踪生育能力的小贴士
持续跟踪您的月经周期以获得更准确的预测。考虑使用额外的生育迹象，如基础体温和宫颈粘液变化。请记住，周期长度可能会有所不同，因此定期跟踪有助于识别您的模式。

常见问题解答
在这里找到关于排卵、月经周期和生育能力跟踪的常见问题的答案。了解如何计算生育力旺盛的日子，理解周期长度的变化，以及影响排卵时间的因素。
计算器根据典型的周期模式提供估算。虽然通常可靠，但实际排卵时间可能会有变化。为了获得最佳结果，请结合使用其他生育追踪方法，并在计划怀孕时咨询医疗服务提供者。
周期变化是正常的。使用您的平均周期长度进行计算，但要跟踪多个周期以了解您的模式。考虑使用额外的生育追踪方法以提高准确性。
It assumes a luteal phase of about 14 days and counts backward from the next expected period. Sperm can survive several days and the egg about a day, so the fertile window is a handful of days around estimated ovulation — not a single hour.
No. Calendar estimates are a poor standalone contraceptive. ACOG discusses fertility-awareness methods that use more than a date calculator. If you need contraception, use a method recommended by your clinician.
Even with well-timed intercourse, monthly conception odds for a given cycle are well below 100%. Age, timing error, semen parameters and health conditions all matter. See a clinician if you have been trying for 12 months (or 6 months if you are 35 or older).
LH tests and cervical mucus track the current cycle; a date calculator only projects from past cycle length. Tests can still false-peak. Many people use both as a rough guide, not a guarantee.
The estimate degrades quickly. Track several cycles, or use a method that observes current fertile signs. Irregular cycles also warrant a clinical check for PCOS, thyroid disease or other causes.
Yes. Illness, travel, night shifts and energy deficit can postpone ovulation, which this calculator cannot see. Treat the date as a prior, not a fact.
The luteal phase is relatively stable for many people but not exactly 14 days for everyone. That assumption is the main error term in calendar methods.
Return of ovulation is unpredictable. Wait until cycles re-establish before trusting a calendar estimate, and ask your clinician about preconception care.

Calendar estimates are priors
Counting back ~14 days from the next period guesses ovulation from a typical luteal phase. The fertile window is several days, not a timestamp. LH kits and cervical mucus observe the current cycle; this calculator only projects from cycle length.
Do not use a date calculator as contraception. If you are trying to conceive and have been unsuccessful on the timeline your clinician uses, book that appointment rather than refreshing this page.
Irregular cycles
Variable cycle length makes the estimate worse, and it can be a medical signal (PCOS, thyroid disease, energy deficit). Track, then talk to a clinician if cycles are consistently shorter than 21 days, longer than 35, or absent.
