Low placenta position in the fifth month of pregnancy is still relatively common in clinical practice. If there are no uncomfortable symptoms, regular pregnancy tests are sufficient and no special treatment is needed. Pregnant women should ensure that they are well rested and not strained in their daily life. In addition, they should pay attention not to do squatting, which may cause the low positioned embryo to be stretched and thus become dangerous. If there are any adverse symptoms such as vaginal bleeding, it is important to seek medical advice and medication to preserve the fetus. The reason for saying that a low placenta in the fifth month of pregnancy does not need to be treated is that the placenta occupies half of the uterine wall in the fifth month of pregnancy, and it is easy to detect a low placenta during an ultrasound. As the lower segment of the uterus continues to be elongated in the middle and late stages of pregnancy, the placenta will in most cases be positioned further and further away from the inner cervical opening. After late pregnancy, the area of the placenta occupying the whole uterine wall will be reduced to 1/3 or 1/4, and the placenta will gradually move up to its normal position. If the ultrasound still indicates low placenta position in late pregnancy, it is called placenta praevia, which should be paid attention to, pay attention to fetal movement, and consult the doctor at any time if there is abdominal pain or bleeding. If the placenta is still low at the time of delivery, it is likely that postpartum hemorrhage will occur, so it is recommended to go to a hospital with better conditions for delivery.
