What does placenta grade I mean? Can I give birth if I have a grade II placenta?

It is said that pregnancy lasts for ten months, but in fact, in many cases, you don’t have to wait until the full ten months to give birth to a baby. Generally, it will be earlier. This is actually related to the maturity of the placenta. There will be a placenta grade based on the maturity of the placenta, which can usually be seen on the B-ultrasound report. So what does it mean specifically?

What does placenta grade I mean?

Placental grading is an indicator of placental calcification, which is generally divided into four grades and will be indicated in Roman numerals on the ultrasound report.

It is generally divided into four levels: Level 0, Level Ⅰ, Level Ⅱ, and Level Ⅲ.

Placenta grade 0 usually occurs before 28 weeks of pregnancy. At this time, the placenta is still immature and the basal layer of the placenta has not yet appeared.

Placenta grade I usually occurs between 29 and 36 weeks of gestation, when the placenta is basically mature.

Placenta grade II usually occurs between 36 and 40 weeks of gestation, when the placenta is mature.

Placenta grade III usually appears after the 38th week of pregnancy. If it appears before the 37th week, precocious placenta should be considered. Because the placenta has aged, calcification and cellulose deposition have begun to appear inside it, which will affect the supply of oxygen and nutrients to the fetus and affect the normal development of the fetus, so pregnant mothers need to pay special attention.

Generally speaking, the placenta is related to the gestational age. From 12 to 28 weeks of pregnancy, the placenta is grade zero; from 30 to 32 weeks of pregnancy, the placenta is grade one; after 36 weeks, the placenta is generally grade two.

Can a secondary placenta be delivered?

When the placenta is at level 2, it indicates that the placenta is becoming mature. Generally, the placenta that reaches this level of maturity occurs between 28 and 36 weeks of gestation, and this is a theoretical value. However, in real life, the placenta often cannot last that long.

If the placenta is already at level 2 maturity, it means that the delivery time will be earlier than normal. Otherwise, if the placenta is stretched for too long and severe calcification or aging occurs, it will have a great impact on the development of the fetus. It is recommended that you should always observe the maturity of the placenta in the late pregnancy. Once the placenta fails, delivery must be carried out regardless of whether there are signs of delivery or whether the fetus is full-term.

How many months of pregnancy does the placenta

Normally, when you have an ultrasound at 5 months, the ultrasound report will show the data of the placenta. It will state whether the placenta is located on the anterior wall or the posterior wall, and how thick the placenta is. When you are more than 20 weeks pregnant, the maturity of the placenta should be shown.

By the 7th week, an embryonic disc of about 2 mm will be formed. At this time, the baby is not yet a fetus, so it can only be called an embryonic disc.

During weeks 12-13, the placenta forms rapidly and continues to grow as the pregnancy progresses.

At 20 weeks, the placenta is 170 grams. At 30 weeks, the placenta is 450 grams. By 40 weeks, the placenta is mature and weighs about 700 grams, which is one-sixth of the fetal weight.

The placenta is the life support system for the fetus, supporting the needs of the fetus through the mother's blood, while also acting as a barrier against infection and harmful substances.
