Is it normal for the placenta to be 30mm from the cervix?

During pregnancy, as the embryo grows and develops reasonably, the distance between the embryo and the cervix will undoubtedly change. However, if the embryo is too low, it is a low placenta, which can easily lead to premature birth or miscarriage. If the embryo is too high, it will directly affect the start of delivery. Therefore, during prenatal check-ups, it is necessary to make a clear determination of the distance between the embryo and the cervix.

1. Is it normal for the embryo to be 30mm away from the cervix?

The outer edge of the embryo is more than 30 mm away from the internal cervical os, which is a normal position. If the placenta is low, the outer edge of the embryo is less than 20 mm from the internal cervical os. In the second and third trimesters of pregnancy, if a low-lying placenta occurs, it will generally return to its normal position after the seventh month of pregnancy. If after 7 months of pregnancy, the outer edge of the embryo is still less than 20 mm from the internal os of the cervix, or if it covers the internal os of the cervix, it is a low-lying placenta or placenta previa, which is abnormal and natural delivery is not possible. A cesarean section is required. If the distance exceeds 30 mm, it will have no effect on the delivery of pregnant women.

2. How much is the distance between a normal embryo and the uterine os?

Normally, the outer edge of the embryo should be more than 7 cm away from the internal cervical os. If it is less than 7 cm, it may be a low placenta. It is also a type of placenta previa. There is no specific treatment for low-lying placenta. The only treatment options are to stay in bed and rest, avoid fatigue, fright and sexual intercourse, and eat more high-protein foods. As the pregnancy progresses, the position of the embryo and the cervix may change. If there is no painless vaginal bleeding, continue to observe and pay attention to the above matters. In addition, it is still possible to grow before 30 weeks of pregnancy. Since external placement can easily cause painless bleeding, you must be extra careful in maintaining the fetus. Be careful to avoid moving hanging objects, do not stand for a long time, stay in bed more, do less activities, try not to hold urine, and prohibit sexual intercourse to prevent or reduce bleeding. If there is bleeding, no matter how much, go to the hospital immediately.

3. The impact of abnormal distance between embryo and cervix

Unexplained, painless vaginal bleeding during late pregnancy or just before labor. Complete placenta previa bleeds early, with heavy and recurring bleeding; some exteriorized and low-lying placentas bleed later and less. Because the placenta is located in the lower part of the uterus, it is easy to cause the fetus to be in a transverse position or the fetal head to float high, which increases the rate of dystocia in pregnant women. If the condition is mild and the bleeding subsides, the baby can be delivered safely. If you encounter this kind of situation, you must calmly cooperate with the doctor and take the initiative to seek treatment. If bleeding is excessive, you should consider terminating the pregnancy as soon as possible. Choose cesarean section for pregnant women to give birth.
