The brown discharge in early pregnancy may be a normal physiological phenomenon, or it may be caused by a disease, which should be treated after the cause is clarified. Common causes and treatments: 1. Fertilized egg implantation: After the formation of the fertilized egg, it will gradually migrate from the fallopian tube to the uterine cavity for implantation in the endometrial muscle vessels. Therefore, in some women, the fertilized egg will cause the rupture of the small blood vessels in the endometrium during implantation, resulting in a certain degree of vaginal bleeding, which may appear as a slight pink or brown discharge that may gradually disappear in 1-2 days. 2. Pre-eclampsia: If a pregnant woman experiences paroxysmal lower abdominal pain accompanied by vaginal bleeding, it may be a pre-eclampsia. When the symptoms are mild, they can gradually disappear after rest and treatment. If vaginal bleeding increases or lower abdominal pain intensifies, it may develop into inevitable miscarriage. Pregnant women should go to the hospital in time for early detection and early treatment, and use drugs for fetal preservation treatment as prescribed by the doctor; 3. gynecological diseases: vaginitis, cervicitis, cervical polyps and other gynecological diseases can also lead to brown discharge in early pregnancy. The vaginal plugging should be done gently to avoid improperly inducing contractions that can lead to miscarriage. The first thing you need to do is to take a look at the following: 1. diet: a balanced and diversified diet, eat fresh fruits and vegetables, take vitamins and pay attention to folic acid. 2. daily life: strengthen your daily hygiene and cleaning care, clean your vulva with water moderately, change your underwear regularly, and wear cotton, breathable clothes and underwear. Relax, work and rest regularly, ensure sufficient sleep and avoid overworking. Forbid sexual intercourse during the first and second trimesters of pregnancy, and conduct regular prenatal checkups to keep track of the development of the fetus and the physical condition of the pregnant woman.
