It is normal to some extent to have blood clots in the first one or two days of menstruation and pink-colored blood on the third day. During the menstrual cycle, the endometrium sheds and is expelled from the body, and the menstrual blood may contain fragments of shed tissue, which can form clots during expulsion. The appearance of blood clots in the early stages of menstruation is usually due to faster blood clotting or heavier menstrual flow. The pink color of the blood on the third day may be due to the mixing of a small amount of old blood or endometrial tissue, which together give the menstrual blood a pink hue.

The presence of blood clots and pink menstrual blood during menstruation is normal to some extent, but this does not mean it is always harmless. Blood clots in menstrual blood are usually caused by faster blood clotting or heavier flow, while pink menstrual blood may result from the mixing of a small amount of old blood or endometrial tissue. However, if the clots are large or the blood color is abnormal—such as dark red, black, or accompanied by an unusual odor—it could be a symptom of certain conditions, such as uterine fibroids, endometriosis, or infection. If abnormal symptoms occur, it is important to seek medical attention promptly to rule out potential health issues.

Health Management Tips:

1. Maintain personal hygiene and keep the vulva clean.

2. Observe changes in menstrual color and texture, and record any abnormalities.

3. Seek prompt medical examination when abnormal symptoms occur.
