The fifth month of pregnancy has entered the second trimester. The fetus is about 25cm long and weighs 300g. At this time, the baby can move naturally in the mother's belly. Through B-ultrasound, you can see the little guy sucking his fingers, which is especially cute!

1. Fetal development

Fetal length: 18-25cm; fetal weight: 160-300g.

It's 5 months pregnant! The baby is feeling comfortable in the womb! The head of the fetus accounts for 1/3 of the body length, the ear openings are open, the gums are beginning to form, and the hair and eyebrows are complete. The fingers and toes grow nails and become raised. The fetus will also lick and suck the thumb with its mouth, as if it is savoring the flavor of its finger.

The nails are ridged and the baby will lick and suck the thumb with his mouth, as if he is tasting the taste of his fingers.

As subcutaneous fat begins to accumulate, his skin has now become translucent, but the subcutaneous blood vessels are still clearly visible, which looks a bit scary! However, his bones and muscles are becoming stronger and stronger, and he is a sturdy little man. The genitals are also clearly visible.

2. Changes in expectant mothers

You have gained a lot of weight, at least 2kg. Your uterus has slowly grown in your abdominal cavity, and the top of your uterus has now reached the level of your belly button. At this time, the thickness of the uterine fundus can be measured at approximately 15-18 cm above the upper edge of the pubic symphysis. By 9 weeks of pregnancy, your uterus will rise 1 cm per week. You should now measure your uterine height (the length from the top of the pubic symphysis to the fundus of the uterus) weekly.

As the uterus grows, the irritation to the bladder is alleviated, so the frequent urination phenomenon basically disappears. The breasts swell more significantly than before, and some pregnant women can even squeeze out a transparent, viscous, watery, and slightly whitish liquid. The buttocks also appear rounder due to the increase of fat, and the appearance begins to appear fuller than before. The early pregnancy reactions will naturally disappear, and your body and mood will feel much better. In addition, pregnant mothers gain at least 2 kg in weight, and some may reach 5 kg.
