The fetus is about 14cm tall and weighs 68g. The average biparietal diameter was 3.23±0.51cm, the average abdominal circumference was 9.13±1.56cm, and the femur length was 1.74±0.58cm.

At this time, the fetus begins to grow eyebrows, and the skin begins to be covered with fetal hair. The fetus's blood vessels can be seen through the thin skin, and it can be seen that the fetus's legs are longer than its hands.

There will be an obvious bulge under your belly button. You will feel the baby's little house about 7.6 to 10 cm below the belly button.

Fifteen weeks pregnancy check

1. Down syndrome screening: You can have a prenatal check-up this week, and the doctor will determine whether the fetus has congenital diseases through examination. If you are a 35-year-old mother, or have experienced miscarriage or stillbirth, you should check it more carefully. It's best to have a Down syndrome screening this week to rule out the possibility that the fetus has Down syndrome. This is a serious congenital defect and must be checked carefully.

2. Check whether the blood types of mother and baby are incompatible: During this prenatal check-up, you need to check whether the blood types of mother and baby are incompatible. If you are type O blood and the expectant father is not type O, the fetus may develop ABO hemolytic disease, but this situation is more common in the first child; the other is Rh incompatibility, which is when your blood type is Rh negative and the expectant father is Rh positive. In this way, during delivery, your blood will produce antibodies to the fetus's blood, which will be dangerous.

3. Protect your oral cavity: Your body’s endocrine system changes after pregnancy, and your gums may become congested or bleeding. If the diet structure is improper or teeth are not brushed in time, periodontitis may be caused. Don't underestimate this situation. Data show that the incidence of periodontitis is highest among pregnant women who suffer miscarriage or premature birth. Therefore, you must pay attention to oral hygiene and treat dental diseases in time.

4. Frequent urination and sweating: You may start to get up to urinate at night, and very frequently. This is because the fetal metabolites increase and put a burden on the kidneys. Don't be afraid to drink water at this time. It is very important to replenish water. Go to the toilet more often for the sake of the baby! And because the blood flow in your skin increases, you will often feel hot and sweat. You can take a few more warm baths every day to ensure hygiene and sweat in time.

5. Appropriate zinc supplementation: You are now responsible for the nutrition of both yourself and the fetus, so zinc deficiency is quite common. Zinc deficiency will cause you to lose appetite and have poor digestion and absorption functions, so eat more zinc-containing foods, such as oysters, sesame seeds, ark shells, etc., especially oysters which have the highest zinc content.

How big is a fetus at fifteen weeks? That means the pregnant woman has been pregnant for more than three months, and the fetus is basically formed and stable. Even so, we must always pay attention to the size of the fetus so that we can know whether the fetus is in a healthy state and whether we need to supplement the body.
