Patient's question:
The menstrual cycle takes half a month to clean up. Sometimes there are blood streaks in the leukorrhea, and sometimes there are none. The legs are sore and weak.Doctor's answer:
During the middle of the menstrual cycle, specifically the ovulation period, a temporary decline in estrogen levels causes the endometrium to lose hormonal support, leading to partial shedding of the endometrium and resulting in regular vaginal bleeding, known as ovulatory bleeding.
