How big is the baby at 9 weeks pregnant

Patient's question:

I have an itchy lower body, and my underwear is always yellow. What's going on? How big will the baby be at 9 weeks of pregnancy?

Doctor's answer:

At 9 weeks of pregnancy, the fetus grows to about 2.15 centimeters in length. The head is larger than the body, and the various organ regions are more distinct. The skull begins to calcify, and the placenta begins to appear and develop. Ultrasound shows that the gestational sac almost fills the uterine cavity, and the overall outline of the fetus is more clearly visible. On March 21, an ultrasound revealed: the uterus is enlarged, and a gestational sac echo measuring approximately 4.12.9 cm was detected within the uterine cavity. The sac contains fetal germ reflection and regular primitive heart tube. The data falls within the normal statistical range. Rest and take care of the pregnancy peacefully.
