更科学的计算方式，帮助你准确计算安全期时间
最好用的计算图表，男人都能看懂的安全期图示

2秒钟确定今天是否能同房！

完美支持iphone6和iphone6 plus大屏。

女性的排卵日期一般在下次月经来潮前的14天左右。
下次月经来潮的第1天算起，倒数14天或减去14天就是排卵日，排卵日及其前5天和后4天加在一起称为排卵期。

女性安全期自测
例如，某女的月经周期为28天，本次月经来潮的第1天在12月2日，那么下次月经来潮是在12月30日(12月2日加28天)，再从12月30日减去14天，则12月16日就是排卵日。排卵日及其前5天和后4天，也就是12月11-20日为排卵期。除了月经期和排卵期，其余的时间均为安全期。
