Next, let’s discuss the fetal development chart at 12 weeks of pregnancy.

12 Weeks Pregnancy Baby Development

This week, the fetus is about 9cm long and weighs 23g. The fetus's life-sustaining organs have begun to function, such as the liver has begun to secrete bile, the lungs have been fully formed, the thyroid gland and pancreas have been fully formed, the liver has begun to produce red blood cells, and the kidneys have secreted urine into the bladder. The posture of the fetus' body is becoming less bent and more straight.

At this time, the reproductive organs of the fetus are basically grown and developed. If there are any deformities, they may be manifested, and the head thickens and becomes more complete. The skull is highly resolved, the biparietal diameter of the fetus can be measured, obvious deformities can be diagnosed, and the internal organs tend to be healthy.

At this time, the growth rate of the fetal head begins to slow down, while the growth rate of other parts of the body gradually accelerates. The fingers and toes have been completely separated, and some bones have begun to become harder and the prototype of joints has appeared.

12 Weeks of Pregnancy: Mother's Transformation

This week you will gain about 0.9kg, your waistline will become wider, and you will begin to look more like an expectant mother. Your breasts will be more full and your bra will need to be one size larger than usual. At the same time, your butt has become bigger, and if you squat almost all day long, you may feel some pain in your coccyx. Your uterus gradually expands as the fetus grows. At 12 weeks of pregnancy, the inner edge of the uterus can be touched between the belly button and the ischial tuberosity.

What nutrients are needed during the 12th week of pregnancy?

Main nutrients: magnesium, vitamin A

Magnesium is not only important for the health of fetal muscles, but also contributes to the normal growth and development of bones. Recent studies have shown that the amount of magnesium consumed during the first three months of pregnancy is related to the newborn's height, weight and head circumference. It is very easy to find magnesium in cooking oils, green leafy vegetables, dried fruits, soybeans, winter melon, cantaloupe, bananas, apples, strawberry sprouts, sunflower seeds and whole wheat bread. In addition, magnesium is also beneficial for the repair of the mother's uterine muscles. Magnesium intake can also prevent complications such as pregnancy cramps and premature birth.

Vitamin A is required throughout the entire process of fetal development, and it especially ensures the health of the fetal skin, digestive tract and lungs. During the first three months of pregnancy, the fetus cannot store vitamin A on its own, so the expectant mother must provide enough. Sweet potatoes, winter melon, broccoli, and mangoes all contain a lot of VA. Under the premise of ensuring nutritional intake, try to avoid unnecessary weight gain.

Diet plan for three months of pregnancy:

Although the third month of pregnancy is a critical period, because the fetus is still small, the nutrition needed is not about quantity, but quality, especially foods high in protein, sugar and vitamins. After 11 weeks of pregnancy, due to the rapid growth and development of the fetus, the nutrition needed also increases.

Due to early pregnancy reactions and the compression of the stomach and other digestive systems by the enlarged uterus, pregnant women often experience indigestion, loss of appetite and other symptoms. At this time, in addition to eating small meals frequently, pregnant women should choose fresh foods that are easy to digest and absorb, and try to avoid eating fried and spicy foods.

The above is a detailed introduction about how big the fetus is at 12 weeks of pregnancy and the fetal development chart at 12 weeks of pregnancy. The pregnancy is about to be three months old. The fetus is now about 16cm long and is busy doing stretching exercises in the mother's belly all day long, stretching its arms and kicking its legs. The pregnancy reaction period will also be over, and the pregnant mother's appetite will begin to improve.
