Brown discharge after ovulation is mainly considered to be ovulatory bleeding. Ovulatory bleeding is mainly due to the patient’s high estrogen level before ovulation, which usually reaches 200 pg/m. After ovulation, the patient’s estrogen level drops rapidly, so the endometrium loses the high hormone level support and will appear to be exfoliated and bleeding. After ovulation, the corpus luteum forms and the corpus luteum secretes estrogen and progesterone, so the level of estrogen and progesterone will rise again. When ovulatory bleeding occurs once in a while, no special examination and treatment is needed. When it occurs three or more times in a row, an examination must be conducted and after excluding organic lesions, you can choose to use contraceptive pills for treatment.
