The placenta is 2 cm away from the cervix

If some pregnant women have problems during pregnancy, they must pay attention to taking timely treatment to prevent the safety of the pregnant women from being affected by the problems. In particular, some pregnant women must pay attention to ensuring the safety of the fetus, especially if there is a problem with the embryo. Whether it is normal for the embryo to be 2cm away from the cervical opening is a problem that many pregnant women are very concerned about.

1. The distance between embryos and cervix is ​​2 cm

How far the embryo is from the internal cervical os is considered normal? There is currently no unified standard internationally. At present in my country, if the distance between the edge of the embryo and the internal os of the cervix is ​​less than 2 cm, it is considered a low placenta, which carries a risk of internal bleeding during pregnancy or delivery. A distance of more than 2cm is relatively safe and allows for natural childbirth. In addition, when the lower uterine segment is formed in the late pregnancy, it will naturally lengthen by 7-10 cm, and the distance between the edge of the embryo and the internal os of the cervix may increase, so that the position of the edge of the embryo can reach a relatively normal and safe distance.

2. What should I do if the embryo is 2 cm away from the cervical opening?

1. If the embryo is close to the internal cervical os, it belongs to placenta previa. Once placenta previa is confirmed, the patient should be hospitalized for observation. Measure blood test, prepare blood test, and rest. Pregnant women usually sleep on their left side to eliminate the compression of the inferior vena cava by the right-rotating uterus, which is beneficial to improve the blood circulation of the embryo. Avoid excessive or rough abdominal examinations, keep the stool soft and smooth, and reduce sudden increases in intra-abdominal pressure. Regular B-type color Doppler ultrasound examinations.

2. The NT (nuchal translucency) test is a test from 11 weeks to 13 weeks and 6 days. If the embryo is low relative to the internal os of the cervix, this week of pregnancy can only indicate a low-lying placenta. As the pregnancy weeks increase, the embryos of most pregnant women will grow upwards. A small number of embryos are low from early to late pregnancy. Then, after 28 weeks, the actual distance between the embryo and the internal os of the cervix will indicate a low-lying placenta or marginal placenta previa. The placenta is low in position, and the probability of bleeding in the late pregnancy will be high. There is no practical way, just avoid larger or more intense exercise. It is still early now, you can observe and if there is bleeding, seek medical attention immediately.

3. In the early and middle stages of pregnancy, the embryo will be close to the internal os of the cervix, but as the pregnancy progresses, the embryo will gradually move. After 28 weeks of pregnancy, the embryo adheres to the lower part of the uterus, and even the outer edge of the embryo reaches or covers the internal cervical os, and its position is smaller than the presenting part of the embryo. This is called placenta previa. Clinically, there will be painless, slowly increasing, recurrent vaginal bleeding without any cause.
