Under normal circumstances, the umbilical cord of a pregnant woman is attached to the center of the placenta, and blood vessels are distributed in sequence to provide good support and nutritional supply to the fetus. But if there is a deviation or abnormality in the attachment position, that is, if the umbilical cord is attached in a sail like manner and becomes a sail like placenta, how many weeks can the sail like placenta be detected?

The sail shaped placenta can be detected under ultrasound, and it takes about three months for a pregnant woman to form a placenta. Therefore, the sail shaped placenta can only be detected at least 12 weeks after pregnancy. Pregnant women with sail shaped placenta should pay more attention in their daily lives, such as adopting a left lateral position when lying down, and reducing frequent activities to prevent premature rupture of membranes.
During pregnancy, it is also important to undergo regular prenatal check ups, strengthen nutrition during pregnancy, and eat more iron rich foods such as red dates, lean meat, and animal liver to prevent anemia symptoms in pregnant women. Due to long-term bed rest, pregnant women should also consume more fruits, vegetables, and coarse grains to increase intestinal peristalsis and prevent constipation, and develop the habit of regular bowel movements.
If a pregnant woman only has a simple sail shaped placenta, she can choose to have a cesarean section during delivery. However, if there is a combination of pre positioned blood vessels, she should be prepared to terminate the pregnancy because pre positioned blood vessels can pose a risk of fetal compression or even death during the delivery process.
