The small gestational sac has always troubled many women, fearing that they may have pregnancy problems. Some women may also worry about a small gestational sac causing fetal arrest. Will a small gestational sac cause fetal arrest? Let's learn about it together.
In fact, the size of the gestational sac varies from person to person, so a small gestational sac will not affect fetal arrest because the gestational sac will continue to grow and there may be fetal sprouts and heart rate. The reason for the small gestational sac may be viral infection or poor development of the fertilized egg. If pregnant women catch a cold, fever, rubella virus, or take medication indiscriminately during pregnancy, it will affect the development of the gestational sac.
Usually, a smaller gestational sac can lead to abnormal ovulation and delayed conception due to emotional stress, resulting in a shorter duration of amenorrhea in the gestational sac. Generally, the size of the gestational sac can be measured using ultrasound to estimate gestational age, and then based on changes in the data, fetal development can be monitored.
At four weeks of pregnancy, the fetus has a small volume of 0.2 centimeters. Five weeks have passed, and the membrane cavity has expanded by 0.4 centimeters and a half. At six weeks to 0.85, various organs began to differentiate. By seven weeks, the fetus had grown to 1.33 centimeters and had already begun to take on human form. Eight weeks to 1.66 centimeters, the tire shape has been determined. From a circumference of nine to 2.15 centimeters, each part is presented more clearly. At ten weeks of pregnancy, it grew to 2.83 centimeters and the embryonic form of the placenta was formed. At eleven weeks of pregnancy, it grows to 3.62 centimeters and the placenta develops.
