Leukorrhea with blood streaks or brownish color during ovulation period

Patient's question:

Leukorrhea with blood streaks or brownish color during ovulation period
Duration and onset of this condition: 2 years
Current general condition: Normal menstruation
Medical history: Previously suffered from cervical inflammation and pelvic inflammation; currently has kidney stones
Previous diagnoses, treatments, and outcomes: June 2005 ultrasound diagnosis of kidney stones and hydronephrosis; no abnormalities found in uterine appendages; intrauterine device position normal; uterine size: 6.7cm x 4.6cm x 4.6cm

Doctor's answer:

Hello, generally speaking, it is normal to have streaks of blood in cervical mucus during ovulation. This is due to a temporary decline in estrogen levels, causing the endometrium to lose hormonal support and partially shed, leading to regular vaginal bleeding.
This bleeding is usually light, with some people experiencing only small amounts of brownish discharge. It typically lasts for half a day or 2-3 days, and in most cases, it does not exceed 7 days. It may be accompanied by mild ovulation pain and lower back discomfort.
