In early pregnancy, there may be a little brown vaginal discharge due to fertilized egg implantation, pre-eclampsia or ectopic pregnancy, but there is no direct connection between brown discharge and pregnancy, because vaginal cervical lesions may also appear as brown vaginal discharge. Women should understand the physiological process of pregnancy and the way to determine pregnancy. The egg discharged by the woman and the sperm ejaculated by the man meet in the abdomen of the woman’s fallopian tube through some sexual act and become a fertilized egg, which gradually moves towards the uterine cavity under the swinging of fallopian tube cilia and peristaltic movement of the fallopian tube, and then further develops and lays. Some pregnant women may experience a small amount of vaginal bleeding or brown discharge, which is normal. Common clinical manifestations of early pregnancy include: menopause (symptoms of early pregnancy, menopause for more than 10 days should be highly suspected of pregnancy), early pregnancy reaction (such as coldness, dizziness, weakness of limbs, drowsiness, nausea and vomiting, dislike of greasy and sour food, etc., mostly appearing around 6 weeks after menopause and disappearing on their own around 12 weeks), frequent urination (the enlarged uterus presses the bladder in front of it, resulting in obvious urge to urinate), breast changes ( The symptoms of breast changes include breast swelling and pain, enlarged nipples and areolas, and deepening of coloring. Women of childbearing age can simply determine whether they are pregnant by the above symptoms, or they can use pregnancy tests or early pregnancy test strips to detect pregnancy. In order to avoid brown discharge due to other diseases, such as pre-eclampsia or ectopic pregnancy, a clear diagnosis should be made at a hospital. Clinically, it is often not difficult to make a diagnosis based on the above clinical manifestations, but if the patient has irregular menstruation and is in the early stage of pregnancy, her complaints are often not well described and auxiliary tests such as blood and urine HCG, progesterone, vaginal ultrasound, etc. need to be taken. If urine HCG is positive or the quantification of blood HCG and progesterone is significantly elevated, and ultrasound indicates early intrauterine pregnancy, the diagnosis can be confirmed. It is worth noting that the ultrasound may not be able to detect the fetal sac in the uterine cavity because the gestational week is too small, so it is recommended to review it after one week. Meanwhile, ectopic pregnancy cannot be ruled out, and pregnant women should pay attention to the presence of abdominal pain and vaginal bleeding, and if lower abdominal pain and vaginal bleeding occur, they should immediately consult a doctor for a definite diagnosis.
