Patient's question:
I have my menstrual cycle delayed by a few days every month. The amount of blood flow is not very heavy, and occasionally there are one or two blood clots during the period, lasting for about 3 or 4 days. In winter, I am particularly afraid of cold. Is this a case of uterine cold? Will it affect fertility? I just got married.Doctor's answer:
Hello, the presence of blood clots in menstrual blood is related to the amount and speed of bleeding.Advice: If you experience heavy bleeding, it may be too fast for the blood to clot properly, resulting in the formation of a blood clot being expelled. Often, the presence of blood clots may indicate that the bleeding volume is relatively high, leading to the formation of a larger clot.
During menstruation, the endometrium is shed, but it may be in small fragments. Blood clots typically originate from the blood vessels supplying the endometrium.
It is common for menstrual blood to contain blood clots. The fragmented endometrium contains certain activators that cause fibrin to break down into fluid degradation products, turning menstruation into a liquid state. Therefore, menstrual blood does not clot.
Sometimes, small clots may also fall off, which are considered blood clots, and this is perfectly normal. However, if accompanied by severe menstrual cramps, it is possible that there is an inflammatory condition. It is recommended to consult a doctor for examination.
