If the monthly period is normal, this time it ends in two days is usually an abnormal situation, and pregnancy can not be ruled out. The shorter days of menstruation may be due to environmental changes and mental factors, generally related to pregnancy, endocrine disorders, lack of sleep, mental tension, etc., and also related to the weakness of liver and kidney, blood and Qi deficiency in Chinese medicine. If you have a history of sexual intercourse during the ovulation period before your menstrual period, it is recommended to check whether you are pregnant through pregnancy test or hCG. If pregnancy is ruled out and you want to regulate irregular menstruation, it is recommended to take relevant drugs orally.
