Women's menstrual period is a fragile stage, so it is recommended not to use it for the time being and wait until the second or third day of menstruation. Some merchants may say, it doesn't matter, it works better during the period, just to make you happy. During the menstrual period, it is recommended that you eat light food and drink plenty of water (to some extent, you can detoxify and lose weight, but you can't drink too much ~), and don't eat ice. If you really can't stand it, eat a little at three in the afternoon. If you can't eat it, don't eat it, which is not good for women's menstrual uterus.
