On the issue of female soldiers not coming to their official holidays,

Hello, it is abnormal not to have menstruation. The menstrual cycle of women is generally 28 ~ 30 days. It is within the normal range to advance or postpone for about 7 days, and the cycle length varies from person to person. But if you haven't menstruated for more than 7 days, it is delayed menstruation. There are two main reasons for delayed menstruation. The first is pregnancy, and the second is irregular menstruation. & ltbr & gt& ltbr & gt Stay up late, overwork, irregular life, anger, depression, etc. These problems will lead to delayed menstruation. Pay attention to rest, eat lightly, don't eat spicy food, and don't catch a cold.
