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 weak and sore.Doctor's answer:
At the middle of the menstrual cycle, i.e., the ovulation period, due to a temporary decline in estrogen levels, the endometrium loses hormonal support and experiences partial shedding of the endometrium, leading to regular vaginal bleeding, which is known as ovulatory bleeding.
