What to check at 13 weeks of pregnancy

When the pregnancy reaches 13 weeks, it is necessary to check the development of the fetus and physical changes to see if they are within the normal range. After 13 weeks, the first thing to do is to check the abdomen and check the bulge of the abdomen. At this time, the fetus is about ten centimeters long and weighs 25 grams. Regular examinations can observe the baby's detailed development.

This week, the fetus is about 10cm long and weighs about 25g. The average biparietal diameter was 2.52±0.25cm, the average abdominal circumference was 6.90±l.65cm, and the femur length was 1.17±0.31cm.

The fetus's fingernails begin to grow and wrinkles begin to form, the roots of the 20 deciduous teeth begin to form, the vocal cords begin to form, and the organs, lungs, stomach, liver, pancreatic islets and other internal organs begin to function. His eyes became more prominent on the forehead of his head, the distance between his eyes decreased, his fingers began to clench into his palms, his toes and soles of his feet could bend, and his eyelids remained tightly closed.

At this time, if the mother gently touches her abdomen with her hand, the baby in the belly will move, but you still cannot feel the movement of the fetus. Although your chances of miscarriage are greatly reduced now, expectant mothers with a history of miscarriage should still be careful. However, you don’t have to worry too much, because the baby is already very strong at this time and he will protect himself for you.
