Placenta previa can be divided into complete placenta previa, marginal placenta previa and placental depression, placental depression and marginal placenta, partial placenta, the most dangerous is complete placenta previa, followed by partial placenta previa and marginal placenta, and placental depression, that is, status placenta, is the slightest placenta previa.
As long as the placenta is less than 6 cm from the pregnant woman's cervix, the placenta is low. As long as the placenta is far enough away from the cervix, it will not affect the delivery of pregnant women.
Complete placenta previa, this is because the placenta completely covers the cervix, so it is impossible to give birth naturally, and it is prone to massive bleeding.
Pregnancy 12 weeks, belonging to the first trimester. At this time, the fetal head and buttocks are 9 cm long and weigh 23 grams. Because the fetus is still young, pregnant women's uterus is rich in amniotic fluid, and the fetal position may change in the second trimester, which is why doctors generally don't diagnose the placenta in the first trimester, because with the increase of gestational age, the lower uterus moves up and the placenta may grow up on its own.
From the 34th week of pregnancy, pregnant women can check the placenta every two weeks. As long as the placenta is more than 4 cm away from the cervix, there is hope for natural delivery. I used to do color Doppler ultrasound once a week to see the change of placenta position. Later, the doctor thought that my condition was suitable for natural delivery, so he tried to give birth.
Pregnant women with placenta previa are prone to irregular bleeding during pregnancy, so pregnant women should stay in bed as much as possible, avoid exercise and overwork, and avoid stimulating abdominal movements. Once pregnant women find bleeding, they need to go to the hospital in time.
Complete placenta previa is more dangerous. Once there is massive bleeding, it will endanger the health of the fetus and pregnant women. After the fetus is full-term, it is best for pregnant women to go to the hospital for labor. If caesarean section is performed before uterine contraction, pregnant women will not be harmed by two crimes.
Placenta previa is not terrible, pregnant women should not be overly pessimistic, eat as usual during pregnancy, exercise less, and pay attention to regular review.
12 weeks B-ultrasound examination showed normal NT and placenta previa. What should I do?
First of all, congratulations to the subject, NT is normal, and then tell you that placenta previa is not really placenta previa.
Pregnancy 12 weeks, the fetal length is about 9cm, and the top and buttocks are 6-7 cm long; The placenta has formed, and the uterus is about the size of a fist. If the implantation position is slightly lower, then under B-ultrasound, the placenta position is lower.
The size of the uterus, with the increase of pregnancy time, the uterus gradually increases, softens and changes greatly. At the time of full-term pregnancy, the volume of uterus reached 35×25×22cm, which increased by 1000 times, reaching 5000ml, and the weight increased by 20 times. When the isthmus of the lower uterine segment is elongated by 7-8 cm, the placenta attached to the uterine wall will move upward with the uterus like the moon, and now it becomes full on the sea surface and gradually moves away from the cervix. At this time, the state before placenta previa no longer exists and becomes the normal placenta position. So the real placenta previa was diagnosed after 28 weeks of pregnancy.
So what now? No sexual life and strenuous exercise, pay attention to abdominal pain and bleeding, and have a checkup on time. If there is bleeding or abdominal pain, go to the hospital for examination in time.
Following the doctor's advice, it is generally safe to spend a long pregnancy and meet the baby.
Thanks for reading.
I am pregnant 13 weeks, and nt is also with low placenta position, bleeding and unexpected abortion. My baby is very depressed these days. Be sure to pay attention to rest, stay in bed as much as possible, and go to the hospital as soon as possible if you feel uncomfortable. On the whole, no problem. I just didn't notice [shed tears]
I used to have placenta previa. Don't do heavy work if necessary. Then, try to stay in bed! It will grow up slowly!
