Three months gestational sac size

Pregnancy is a complicated process. After the egg is fertilized, it enters the uterine cavity, and the embryo and attachments develop rapidly to perfection. There are different changes in each week of pregnancy. By referring to the fetal sac chart, you can see whether the fetus can grow and develop normally. Regarding the development process of the fetus, I believe that the expectant mother is most interested. So what does the gestational sac look like in three months? Next, let’s take a look at the detailed content introduction.

Entering the first week of the third month of pregnancy (week 9), that is, in the 9th week of pregnancy, the fetus is about 25mm in size, and many positions of the fetus have changed, including the head, arms and legs, and genitals.

In the second week (week 10), the size of the fetus can reach 4x250m and look like a bean pod. This week, the growth of the baby's wrists and ankles is progressing and visible, and the baby's other parts have also grown to a certain extent. The baby's eyelids are glued together, and the baby's fetal blood is already mature.

In the third week (week 11), the size of the fetus can reach 40-6x250m, and the weight of the fetus can reach about 14 grams. The baby's growth rate may become more and more obvious from this week, and pregnant mothers do not need to worry too much about miscarriage from this time. Now the baby's fingers and toes are clearly visible. From this week on, the baby will start to move in the mother's belly, but of course the pregnant mother still cannot feel the baby's movement. The third month of pregnancy is the time when the baby's bone growth accelerates, so pregnant mothers should increase calcium supplementation during the third month of pregnancy.

In the fourth week (the 12th week of pregnancy), the size of the fetus can reach 65mm. This week, all the bronchial tubes of the baby begin to function, such as the liver begins to secrete bile. The kidneys metabolize urine into the bladder. Then in the last cycle of the third month of pregnancy, the size of the fetus will increase to about 75mm, and the baby's weight will increase compared to before. During this month, the baby's fetal movement can still be seen through B-ultrasound, but the expectant mother cannot feel it.
