The appearance of brown blood every now and then after IVF pregnancy may be due to chronic inflammation of the cervix or columnar epithelial ectopia, bleeding from embryo implantation, and extravasation of blood from the uterine cavity.
1. Chronic inflammation of the cervix: usually brown blood appears on the day of transfer, when there is chronic inflammation of the cervix or columnar epithelial ectopia, the symptom of vaginal brown blood will appear after cervical sterilization, or a shorter period of time after embryo transfer.
2. Bleeding from embryo implantation: If brown blood appears 5-7 days after embryo transfer, it is usually caused by embryo implantation during embryo transfer, which is manifested as a small amount of vaginal bleeding, and after the action of microorganisms in the vagina, it manifests as brown blood.
3. Uterine blood discharge: after IVF, there may be a small amount of blood in the uterine cavity, which is gradually discharged with uterine contraction, but after the action of various microorganisms in the vagina, it eventually manifests as brown blood.
If brown blood appears every now and then after IVF pregnancy, it may be due to chronic inflammation of the cervix or columnar epithelial ectopia, bleeding from embryo implantation, and exocytosis of blood accumulated in the uterine cavity. Pregnant women are generally advised to seek timely medical examination to rule out ectopic pregnancy and other adverse pregnancy outcomes, and to clarify the cause of the disease early for symptomatic treatment.
