So can you get pregnant during your period?

所以，大姨妈来的时候究竟能不能怀孕？

The odds of getting pregnant during your period are extremely low, but it can (and has) happened. During your period, the part of the menstrual cycle when the egg is released and therefore has the potential to unite with a sperm (aka ovulation) is still several days away. But there are exceptions. According to the American Pregnancy Association, "If you happen to be one of the individuals who has a shorter cycle, there is a chance you could get pregnant while having sex during your period."

经期怀孕的可能性非常低，但的确是有可能发生的（而且也的确发生过）。大姨妈期间，排卵并有可能与精子结合的月经周期部分可能还要过几天才会发生。但也有意外。据美国怀孕协会表示，"如果你的经期较短，那在经期发生性关系就有可能使你怀孕。"

This means that the time between your period and your ovulation is closer together. Sperm can live inside of you for up to five days after it is released, so if you have sex toward the end of your period, it would hypothetically be possible to conceive four or five days later with your early ovulation. "The probabilities of getting pregnant while on your period are low, but the possibilities are there," says the APA.

这就意味着你的经期和排卵期相近。精子排出后能够在你身体内存活长达5天的时间，所以如果你在经期快要结束时发生性关系，理论上而言，这些精子可以与四五天后较早排出的卵子结合。"经期怀孕的可能性很低，但还是可能的，"美国怀孕协会的人员说道。
