A small amount of brown discharge in the early stage of pregnancy is normal if there are no other uncomfortable symptoms, but if the brown discharge continues to increase, accompanied by abdominal pain and other symptoms is not normal, you should consult a doctor immediately. At the beginning of pregnancy, placental trophoblast cells produce human chorionic gonadotropin, and estrogen and progesterone levels are at a high level, resulting in the shedding of epithelial cells of the vaginal mucosa, secretion increases, and if the vagina is in a longer period of time, it will become brown, which is a normal phenomenon. However, if the brown discharge persists, there is blood coming out, or abdominal pain, severe vomiting and other symptoms, we should be alert to the possibility of ectopic pregnancy, miscarriage or hyperemesis gravidarum and other diseases, and we should seek medical attention immediately. After the first discovery of pregnancy, the first examination should be carried out promptly to determine the development of the fetal sac and whether the pregnancy is intrauterine. During pregnancy, you should pay attention to rest more, and at the same time, you should relax and avoid tension and anxiety. Any discomfort should go to the hospital in time, so that the doctor can make a clear diagnosis and cooperate with the doctor to deal with the symptoms.
