Pink discharge after menstruation may be caused by undrained menstrual blood, withdrawal bleeding, ovulation bleeding, cervical lesions and so on. 1. Pink discharge after menstruation: If pink discharge occurs within 1 to 2 days after menstruation, it is mainly considered that the menstrual blood has not been completely discharged and the endometrium has not been completely repaired, so pay attention to maintaining cleanliness and hygiene to avoid infections. 2. Withdrawal bleeding: If you have taken emergency contraceptive pills after menstruation, after you stop taking the pills, the hormone level of your body will decrease, resulting in withdrawal bleeding, which can be manifested as pink discharge. 3. Ovulatory bleeding: If pink discharge occurs about 10 days after the end of menstruation, it is mostly considered to be related to ovulatory bleeding. When the hormone level of a woman’s body decreases after ovulation, the endometrium loses the support of estrogen, and may shed, resulting in a small amount of bleeding and the appearance of pink discharge. 4. Cervical lesions: diseases such as cervical polyps, cervicitis, uterine submucous fibroids, cervical cancer and other diseases can cause damage to the mucous membrane, resulting in a small amount of bleeding, manifested as pink discharge, mostly accompanied by abdominal pain, contact bleeding, increased secretion and other symptoms. If there is pink discharge after menstruation and it is not relieved for a long time, it is recommended to go to the hospital in time, improve the gynecological ultrasound and other examinations, make a clear diagnosis and then actively treat it, so as to avoid delaying the condition.
