Presently, the most common kind of hormonal contraception is the combined pill, which contains oestrogen and progesterone.

目前，最常见的激素避孕药是复方避孕药，其中含有雌激素和黄体酮。

And we also have hormonal contraception, which gives us a thinner lining of the uterus, so there's less prostaglandins produced and with less blood, there's less need for cramping.

我们还有荷尔蒙避孕药， 它让我们的子宫内膜更薄，所以产生的前列腺素更少， 血液也更少， 所以不太需要抽筋。
