At 12 weeks of pregnancy, the lower edge of the placenta covers the internal cervical os

At 12 weeks of pregnancy, the lower segment of the embryo covers the internal cervical os, indicating that the placenta of the pregnant woman is relatively low, which makes it very easy for placenta previa to occur in the late pregnancy. For some pregnant women, the position of the embryo will recover as the pregnancy grows, but they need to go to the hospital for regular follow-up and closely monitor the changes in the position of the placenta.

Pregnancy is a unique physiological process for women. During pregnancy, women are particularly concerned about the changes in every part of the body. After a woman has been pregnant for 2 months, she will go to the hospital for relevant imaging tests to diagnose whether it is an intrauterine pregnancy. Recently, a female friend took her B-ultrasound examination report of 12 weeks of pregnancy to consult a doctor online: What does it mean that the lower segment of the embryo covers the internal os of the cervix at 12 weeks of pregnancy? Now we will explain this issue in detail, hoping to be helpful to everyone.

The embryo is the most important tissue structure in the mother's belly during pregnancy. It is the bridge for the fetus to exchange nutrients with the outside world. The area where the embryo grows and transfers in the uterus is the site of embryo implantation. Some pregnant women found that the lower segment of the embryo covered the internal cervical os during color Doppler ultrasound examination in the early stages of pregnancy, which means that the position of the embryo is very low. The medical term is called low placenta.

Under normal physiological conditions, when a woman is pregnant, the area where the sperm and egg are implanted should be in the upper 1/3 of the uterine cavity. If the site of embryo transfer appears in the middle and lower 1/3 of the uterine cavity, it is considered abnormal. This type of embryo abnormality may be temporary. Clinically, it has been found that for some pregnant women, as the pregnancy progresses, the position of the embryo will gradually move away from the internal cervical os and return to normal. However, some pregnant women may develop complete placenta previa in the late stages of pregnancy. Therefore, pregnant women who are found to have a low-lying placenta at 12 weeks of pregnancy are advised to go to the hospital for regular follow-up.

Based on the above introduction, what does it mean when the lower segment of the embryo covers the internal os of the cervix at 12 weeks of pregnancy? We have already explained this issue to you. At 12 weeks of pregnancy, the lower segment of the embryo covers the internal cervical os, indicating that the placenta of the pregnant woman is relatively low, which makes it very easy for placenta previa to occur in the late pregnancy. For some pregnant women, the position of the embryo will recover as the pregnancy grows, but they need to go to the hospital for regular follow-up and closely monitor the changes in the position of the placenta.
