Patient's question:

Menstruation has lasted for more than ten days, and it hasn't stopped yet. Is it possible to be pregnant? Urgent

Doctor's answer:

Menstruation does not lead to pregnancy. The causes of excessive menstrual bleeding are due to a weak constitution, insufficient middle Qi, dietary and physical exhaustion, prolonged illness damaging the spleen, leading to spleen deficiency and qi weakness, causing the leakage of qi, water, blood, and fluid. A naturally excessive yang constitution, extreme emotions, the transformation of five emotions into fire, excessive consumption of spicy foods, external exposure to heat, heat accumulating in the meridians, forcing blood to flow excessively. Improper overexertion during the menstrual period, prolonged blood stagnation, postpartum blood stasis, and the inability of new blood to return to the meridians are factors that contribute to this condition.
Treatment for this condition should focus on nourishing yin, cooling blood, promoting blood circulation to resolve stagnation, replenishing qi to arrest bleeding, and consolidating the meridian to stop bleeding. If the menstrual period lasts excessively long, the best way to check for conditions such as uterine fibroids, ovarian cysts, or gynecological inflammation is to undergo examination.
