The position of the placenta during pregnancy determines the development of the fetus. As for whether it is better to have placenta previa or placenta posterior, placenta previa is very dangerous, but there is currently no obvious research on placenta posterior. Whether it is placenta previa or placenta posterior, as long as the fetus is monitored, it is fine. Normally, the placenta is attached to the posterior wall, anterior wall or lateral wall of the uterine body. If the placenta is attached to the lower segment of the uterus, or even the lower edge of the placenta reaches or covers the internal cervical os, and its position is lower than the fetal presenting part, it is called placenta previa. Placenta previa is divided into complete placenta previa, marginal placenta previa and partial placenta previa; placenta previa is one of the main causes of bleeding in late pregnancy and a serious complication during pregnancy. Improper treatment can endanger the life safety of mother and child. If you are found to have placenta previa during an ultrasound examination in mid-pregnancy, don't be nervous. As the pregnancy progresses, the placenta may gradually "drift" to a position away from the cervical opening, which is not a big deal. If placenta previa is discovered later in pregnancy, it is still possible for the placenta to move out of the cervix; however, the later it is discovered, the less likely it is. The doctor will tell you to have a follow-up ultrasound at the beginning of the third trimester (the last 3 months of pregnancy) to check the position of the placenta. If you have vaginal bleeding at this stage, you should have an ultrasound examination immediately to find out the cause. |
