Women need to do the following when they have their period, especially when they have their first period. First of all, go to the supermarket or kiosk to buy sanitary napkins and put them on your underwear so that menstrual blood will not flow onto your underwear or outer pants and cause infestation. You must be careful when you have your period and avoid eating spicy, stimulating and cold foods. Usually, the sanitary napkins should be changed every two hours and do not engage in strenuous activities during menstruation. At the same time, pay attention to rest, avoid staying up late and straining, and do not play basketball, running, etc. When you have your period, you must pay attention to rest in bed as much as possible to avoid overexertion and abdominal pain and other discomfort.
