If the placenta is low and bleeding repeatedly at 14 weeks of pregnancy, you need to take proper rest, keep the fetus alive, prevent infection, and follow the doctor’s instructions to review on time. At 14 weeks of pregnancy is the middle stage of pregnancy, at this time the ultrasound examination suggests that the placenta position is low and causes repeated vaginal bleeding, you need to pay attention to appropriate bed rest under the guidance of the doctor, reduce the amount of activity, keep the vulva clean and dry, give birth control treatment to inhibit contractions, give antibiotics such as cefazolin sodium and other antibiotics to prevent infection, and check the ultrasound on time. In the middle of pregnancy, the placenta covers 2/3 of the uterine cavity, and when ultrasound suggests that the lower edge of the placenta reaches or covers the endocervical opening, it can only be diagnosed as placenta previa. As the uterus enlarges and the lower segment of the uterus forms, the placenta may move up with the uterus to a normal position. However, when the placenta is still in a low position after 28 weeks, it is necessary to strengthen the management of pregnancy and terminate the pregnancy at the appropriate time according to the condition of the mother and fetus and vaginal bleeding. Repeated bleeding with low placenta at 14 weeks of pregnancy requires active medical consultation and reasonable treatment as prescribed by the doctor.
