12 week fetus picture

At 12 weeks of pregnancy, the fetus is about 9 cm long, 6.1 cm long from top to bottom, and weighs about 14 grams. At this time, the fetus's reproductive organs have begun to grow and the limbs can move. The embryo has already grown and developed to maturity, replacing the role of progesterone in pregnancy. Most of the early pregnancy reactions of pregnant women are alleviated, and some of them disappear, and there is not much change in the weight of pregnant women. After 12 weeks of pregnancy, the enlarged uterus gradually becomes symmetrical and exceeds the pelvis, and can be touched on the ischial tuberosity. The isthmus of the pregnant woman's uterus gradually flexes, stretches, lengthens and softens, and expands into a part of the uterine cavity.

The 12th week of pregnancy is the third month of pregnancy. On the 12th week, the fetus is about 9cm long, 6-7cm long from top to bottom, the sex of the reproductive organs can be initially identified, and the fetus's limbs can move. At 12 weeks of pregnancy, the fetal heart rate can be detected using a Doppler fetal heart stethoscope. When everything is normal, it is 120-160 beats per minute. During the 12th week of abdominal examination, the uterus can be touched on the ischial tuberosity. The height of the uterine fundus measured by hand is 2-3 horizontal fingers above the ischial tuberosity. Gynecological examination shows that the uterus at 12 weeks of pregnancy is 3 times that of the non-pregnant state.

When a woman is 12 weeks pregnant, the fetus has already begun to show human shape, and the fingers and toes are completely separated. At this time, the weight of the fetus is about 23 to 25 grams, and the body length of the baby is generally about nine centimeters. If you check the nt at this time, you can already see the fetal skull halo, measure the size of the fetal biparietal diameter, and see the thickness of the neck clarity, which is usually less than 2.5mm. In addition, you can see the condition of the fetal nose bridge from the B-ultrasound. Generally, basic card establishment and blood tests are required for comprehensive examination at 12 weeks of pregnancy.

At 12 weeks of pregnancy, the baby's head-to-hip diameter is 5.3cm, and the fetal biparietal diameter is 2.0cm. The baby should be registered at 12 weeks of pregnancy, and the baby's NT value should also be accurately measured. Relevant tests need to be done when establishing the registration, such as routine blood test, routine urine test, routine leucorrhea test, liver and kidney function test, routine coagulation test, five eugenics tests, full set of thyroid hormones, thalassemia screening, electrocardiogram test, cervical cancer screening, etc., so as to understand whether the child's development is affected. During this time period, you need to pay attention to diet, balance your diet, and ensure the intake of protein and vitamins, which is beneficial to the development of children.
