Before 12 weeks cannot be called placenta praevia, it can only be said that the placenta is in low position, the low position of the placenta cannot be adjusted by artificial methods, but with the gradual development of the fetus and the placenta, the position of the placenta will gradually move upward, and it may even develop into a normal position of the placenta.
A low lying placenta at around 12 weeks is subject to change. As the weeks of pregnancy increase, the fetus and placenta gradually develop and the lower part of the uterus elongates, the position of the placenta will gradually rise with the enlarged uterus. It is possible for the placenta to progress from complete coverage of the cervix to partial placenta previa, borderline placenta previa, or even a normally positioned placenta.
Therefore, pregnant women with low lying placenta around 12 weeks do not need to worry excessively, as long as they have regular checkups. If pregnant women with placenta praevia experience vaginal bleeding, they need to go to the hospital for examination and treatment in time.
