The menstrual cycle is longer than just the portion you bleed and feel pain for. Your ovaries release the egg (ovulation) for which your uterus then builds a soft, spongy lining in case the egg gets fertilized (pregnant); if it isn’t fertilized, you get your period since you shed the lining. This is what causes the bleeding that we’re all familiar with. The cycle repeats each month. Fun, right? Not really because a lot of women have discomfort and pain during their menstruation.
月经周期比你流血和感到痛经的时间要长。你的卵巢排出卵子，在卵子受精（怀孕）的情况下，你的子宫会长出柔软富有弹性的内膜；如果卵子未受精，因为子宫内膜脱落，你就会来月经。这就是造成流血的原因，我们都很了解。月经周期每个月重复一次。很有趣，是不是？并非如此，因为大多数女性在月经期间会感到不适合疼痛。
It’s also important to remember that every woman’s menstruation is different and unique, periods vary in duration, consistency of timing, how heavy/light the flow is, and the symptoms and pain you feel. Not only are periods unique for every person, but your period can also be completely different month to month. It all depends on your life (i.e stress, what you do every day and your diet), hormones and body.
而且重要的是记住每个女性的月经周期都不同，而且是独一无二的，月经的持续时间，时间稳定性，出血量多少，以及感觉疼痛的症状都是不同的。月经周期不仅对于每个人来说都是独一无二的，而且你的月经可能每个月和每个月都会完全不同。这完全取决于你的生活（例如，压力，每天所做的事情以及饮食），荷尔蒙和身体。

许多女性的经期疼痛都是温和的，但是许多女性的痛经症状是极其疼痛的。这种疼痛是在一个具体的点的剧痛或者更加令人无法忍受，但是也会扩散到不同的点。也有两种不同类型的经期痉挛。
Primary Dysmenorrhea is a common type of menstrual cramps that is caused by getting your period; it isn’t a disease, illness or condition. This type of menstrual cramp can cause mild to severe pain in your stomach, back and thighs a few days before your menstruation and lasts for roughly 12-72 hours. Primary Dysmenorrhea is common in younger women and often becomes less severe with age and after childbirth.
原发性痛经是一种常见的经期痉挛类型，这是由月经造成的；这不是一种疾病。这种类型的经期痉挛会导致你的胃，背和大腿在例假来临几天之前的温和甚至严重的疼痛，而且会持续大概12-72个小时。原发性痛经在年轻女性中比较常见，往往会随着年龄增长以及生育之后疼痛减轻。
