Fetal development chart at the ninth week

Many pregnant mothers who have just become pregnant are very worried about the growth and development of their babies in their belly. Many pregnant mothers will ask anxiously, I am nine weeks pregnant, why there is no sign of my abdomen growing bigger in the past few days? How big is a baby at nine weeks? Since the pregnancy is not long, the baby will not seem to grow that fast. So how big is the baby in the nine-week fetus?

How big is the baby at nine weeks?

1. The pregnant woman's abdomen is generally not visible at 9 weeks of pregnancy, but the hip circumference may expand a little.

2. At the 9th week of pregnancy, the uterus has expanded by 2 times and is about the size of a badminton. The pregnant woman's body shape may change at this time, and her weight will not increase much, but she will find that her hip circumference has increased a little.

3. You can’t tell that you are a pregnant woman.

So how long does it take for a pregnant woman's belly to become visible?

1. Generally speaking, the abdomen does not expand significantly in the first two months of pregnancy, but it gradually increases in size in the third and fourth months of pregnancy.

2. Until the fourth month of pregnancy, the pregnant woman's abdomen begins to expand, with the uterine height ranging from 16 to 20.5 cm and the fetal abdominal circumference beginning to expand at a rate between 76 and 89 cm.

3. Until the pregnant woman gives birth, the height of her uterus should be 32.0-38.5cm, and the fetal abdominal circumference should be 89~100cm. But because every pregnant woman is different, the size of her belly is also different. Experts say that as long as the various indicators of the fetus are normal, there is no need to worry about the size of the abdomen during pregnancy.

It is not difficult to see that the size of the nine-week fetus will vary, and the size of the abdomen may also vary depending on the physical fitness and diet of the pregnant woman. For some people, only their hip circumference may become a little bigger. At this time, there is no need to worry too much, relax, stay happy, replenish the nutrients needed during pregnancy in time, go to the hospital regularly for a comprehensive check of the baby's growth and development, and then wait quietly for the newborn to be born.

Stomach pain is a normal physiological need in early pregnancy. As the uterus enlarges and stimulates the bones, pregnant women will feel a dull stretching pain in the abdomen. But it should be noted that if persistent abdominal pain is accompanied by bleeding symptoms, you should be hospitalized for examination immediately. This physiological abdominal pain may be a sign of miscarriage or ectopic pregnancy. Therefore, when abdominal pain occurs in early pregnancy, we must learn to distinguish between physiological abdominal pain and physiological abdominal pain.

Is the gestational sac irregular and has no fetal heartbeat at nine weeks?

If there is nothing wrong with the pregnancy days, and an ultrasound examination at 9 weeks of pregnancy shows no fetal heartbeat, this means that the test tube embryo tissue has stopped growing and there is no hope of a safe pregnancy. If it is confirmed that the growth and development of the test tube embryo tissue has terminated, then you need to have an abortion as soon as possible to prevent the necrotic test tube embryo tissue from staying in the uterine cavity for too long, causing intrauterine infection or internal bleeding.

This is a slower growth and development, but it can still be observed again. It is now 1-2 weeks late, and it is still possible to grow normally. The suggestion is to wait for a follow-up visit next week. If there is still no fetal heartbeat at 10 weeks, you can consider terminating the pregnancy.

Women must pay attention during the ninth week of pregnancy. At this time, the growth and development of the fetus will gradually improve, so they need to adjust their lifestyle and eating habits in the ninth week. In the ninth week of pregnancy, when the baby is developing well, you should replenish water in time to ensure the normal growth and development of the fetus's bones and teeth. You should also get enough sleep to avoid oral problems. Rubella vaccine cannot be given at this time. Mothers may experience edema in their breasts and need immediate medical attention.
