If your period is delayed due to a recent cold or too many cold drinks, it is recommended to drink more hot water or hot brown sugar water. Pay attention to the warmth of the abdomen and apply a hot water bag to the abdomen to help promote the onset of menstruation. If the late menstruation is caused by excessive emotional stress or anxiety, it is recommended to soothe your mood and drink water with rose flower or take Chinese medicine such as Prozac under the guidance of a doctor, which has the effect of de-stressing the liver and activating blood circulation, which is beneficial to the discharge of menstruation. If the lack of luteal function causes menstruation or even amenorrhea, it is recommended to treat it by injection under the guidance of a specialist. Some women have delayed menstruation due to excessive dieting or anemia caused by an unbalanced diet. It is recommended to enhance nutrition and eat more red dates, pig liver, lean meat and eggs to nourish the blood and promote the onset of menstruation.
