How big is the fetus at three months of pregnancy? The changes of the expectant mother are unexpectedly

After the fetus enters the third month, its growth and development begins to accelerate. By the end of the month, it is about 9cm long and weighs 23g. If an ultrasound examination is performed, it can be surprisingly found that the embryo at this time has begun to take on a human form, and the original tadpole tail will no longer appear.

1. Fetal development

The fetal length is 2 to 9 cm and the fetal weight is 9 to 23 g. The cheeks, jaw, eyelids and earlobes have developed and the face looks more like a human face.

9 weeks pregnant: The fetus is about 2cm long and still very light, about the size of a grape. The fetal head is larger than the fetal body, each part appears clearer, the skull begins to calcify, and the placenta begins to develop.

10 weeks of pregnancy: The baby is about 4cm long, the head-to-hip diameter is about 3-5cm, and the weight is about 13g.

11 weeks of pregnancy: The fetus grows to 6cm, the fetal organs develop further, and the placenta develops. B-ultrasound showed that the gestational sac had completely disappeared and the placenta was clearly visible.

12 weeks of pregnancy: The fetus grows to 9cm and weighs 23g.

At this time, the baby's tail has completely disappeared! It already has a human form, and its growth rate is becoming more and more alarming. The body and legs have grown, but the head is still obviously larger. More importantly, the nose, gums, and vocal cords have grown, and the face can be recognized. The fetus' fingers and toes are completely separated, and the eyes, fingers and toes are clearly visible. Some bones begin to harden, and hair and nails begin to grow.

The fetus's skin is still transparent, so the subcutaneous blood vessels and internal organs can be seen from the outside. Organs such as the heart, liver, and stomach develop more fully. At this point, the shape of the external genitalia has been formed, but the gender cannot be clearly determined. Keep the secret until the baby is born, and you can reveal it yourself!

3. Changes in pregnant mothers

In the third month of pregnancy, your uterus is as big as a fist, but the bulge in your belly is still not obvious from the outside. You may find that your breasts are much larger, more tender, and your nipples and areolas are darker in color. Now you need to use a new bra and wear loose, comfortable clothing that is not too tight around your waist and abdomen.

Now, your morning sickness will gradually disappear, your appetite will begin to increase, and the amount of food you eat will also increase. Due to the congestion in the pelvic cavity and the continuous and vigorous secretion of progesterone, vaginal secretions are slightly more than usual, and frequent urination will occur, with a feeling of incomplete urine discharge.
