12 week fetus size picture

At 12 weeks of pregnancy, the fetus is about 9 cm long, the biparietal diameter is around 1.9-2.2 cm, the crown-rump length is between 6 and 7 cm, the gender can be identified from the reproductive organs, and the fetus's limbs are already able to move. In the early stages of pregnancy, you should pay attention to adequate rest, avoid strenuous activities, and refrain from sexual intercourse to prevent miscarriage. After more than 12 weeks, you can take a multivitamin with folic acid tablets orally, and pay attention to supplementing iron, taking 60 mg a day. Eliminate the radiation source environment and its harmful substances to reduce the occurrence of fetal malformations.

The human embryo 8 weeks after fertilization is a test tube embryo, which is the stage where its key human organ structures are dividing. The fetus is called a fetus from 9 weeks after fertilization, which is the stage when its internal organs continue to grow and develop. On the 12th week, the fetus is about 9cm long, 12cm long from top to bottom, and weighs about 14g. The limbs can move and the reproductive organs have grown and developed. It is recommended to avoid emotional excitement and fatigue during pregnancy, eat more fresh vegetables and fruits, eat less greasy fried foods, exercise moderately, and go to a reliable obstetrics department for regular prenatal checkups.

The size of the baby at 12 weeks of pregnancy needs to be checked by ultrasound. Through ultrasound examination, the fetal biparietal diameter and femoral head length can be accurately measured to determine the size of the fetus. At 12 weeks of pregnancy, a fetal biparietal diameter of about 2.0 cm and a femoral head length of about 0.8 cm are considered normal. By the 12th week of pregnancy, the uterus has already expanded beyond the pelvis. The fundus of the uterus can be touched from the pregnant woman's abdomen. The fetal heartbeat can be heard in the pregnant woman's abdomen through the Doppler fetal heart monitor, and then there is no need to only do ultrasound to determine the size of the fetus.

At 12 weeks, every organ of the fetus's body has basically formed, the fingers and toes have basically separated, and some bones have begun to harden. The fetus weighs about 23g and is about 9 to 10cm long. At this time, you can start going to the hospital for the first prenatal check-up and create a personal file, do some basic tests, such as blood tests, blood pressure tests, urine tests, etc., to rule out common diseases during pregnancy. If necessary, you can also do some genetic tests to determine the gestational age, delivery date and the physical condition of the fetus. At this stage, you must ensure a nutritious diet to avoid excessive weight gain and excessive nutrition that may cause the fetus to be too large.
