Who uses the 排卵期计算器?

  • 正在尝试怀孕的夫妻想要确定每月的最佳生育天数。
  • 女性追踪月经周期以了解健康状况和识别规律。
  • 那些谨慎使用生育意识方法进行自然家庭计划的人。

How the 排卵期计算器 works

1

输入你末次月经的第一天。

2

输入你的平均周期长度(天数)(21–35天,默认28天)。

3

计算器会自动更新,显示你预计的排卵日期、易孕窗口期和下次月经日期,以及一个可视化的月经/易孕/排卵日历。

Tips & tricks

  • 没有单独的黄体期长度输入——计算器始终假设固定的14天黄体期,并将你的排卵日推导为(周期长度−14)。
  • 周期长度限制在21–35天之间;超出此范围的输入将无法计算。
  • 当你更改周期长度字段时,结果会实时更新——无需再次点击计算。

Frequently Asked Questions

易孕窗口期是什么时候?

显示的易孕窗口期是排卵前5天加上排卵当天本身——共6天窗口期。这考虑了精子的存活时间(5天)和卵子释放后的短暂寿命。

28天周期中我什么时候排卵?

在典型的28天周期中,排卵大约发生在第14天(从末次月经第1天算起)。该工具将其计算为周期长度减去14天,所以30天周期得出第16天,26天周期得出第12天,以此类推。

我可以单独输入黄体期长度而不是周期长度吗?

不可以——没有单独的黄体期输入字段。计算器始终假设固定的14天黄体期,并将排卵日推导为(周期长度−14),这对大多数人来说是一个合理的估算,但无法反映异常长或短的黄体期。

这个计算器能帮助避孕吗(自然家庭计划)?

该工具根据周期长度识别预计的易孕窗口期。然而,周期长度每月都会变化,这使得预测作为唯一避孕方法并不可靠。请咨询医疗保健提供者以获取家庭计划指导。

如果我的周期不规律怎么办?

该工具只接受21到35天之间的周期长度。如果你的周期超出这个范围或每月变化很大,基于日历的预测(无论是这个工具还是任何类似工具)都会变得不太可靠——对于不规律的周期,排卵检测试纸(OPK)测试更准确。
