What is the cause of bleeding after sex 42 days after delivery?

Generally speaking, women will stop having lochia in about 6 weeks after giving birth. If after 6 weeks you are still having lochia mixed with blood, you may want to consider whether an infection has occurred and whether your uterus has recovered well. In fact, sometimes postpartum lochia can be prevented through some methods, such as active prenatal examinations for high blood pressure or anemia that may affect pregnancy. Let's take a look at the reasons that may lead to postpartum lochia.

If there is residual tissue and B-ultrasound examination shows a light mass in the uterus, then a uterine curettage must be performed. Women who have had a normal delivery can undergo a uterine curettage directly. If the woman has had a cesarean section, it is recommended that a uterine curettage be performed under B-ultrasound positioning, which is safer. After the operation, treatment should be given to prevent infection and promote uterine contraction. Poor postpartum uterine involution, B-ultrasound often shows an enlarged uterus, fluid accumulation in the uterine cavity, and a high possibility of blood accumulation. Due to poor postpartum uterine contraction, there is residual fluid and blood in the uterus, which leads to irregular vaginal bleeding. If this is the case, oxytocin must be injected intramuscularly or intravenously, and then Chinese medicine should be used to promote uterine contraction. If necessary, oral antibiotics should be taken to prevent infection. Adherence to breastfeeding is beneficial to postpartum uterine contraction and involution.

Postpartum infection leads to endometrial inflammation and postpartum lochia. If this is the case, routine blood tests will indicate an increase in white blood cells and neutrophil ratio. Ultrasound examination often shows no obvious abnormalities. In this case, intravenous anti-infection treatment is required. If breastfeeding is carried out, it is best to use a third-generation cephalosporin antibiotic combined with metronidazole intravenous drip for 3 to 5 days.

Female friends should pay attention that after giving birth, the lochia that flows out every day should be carefully observed, for example, to see whether the color of the lochia is normal, whether the amount of lochia is too much, to smell the foul smell to see whether it is normal, whether it has a bloody smell, or whether it has a foul smell. If any abnormality is found, you should go to the hospital for examination and treatment as soon as possible.
