An ultrasound can now reveal your baby’s sex
Your baby’s genitals are now formed [1]. Although the boys' testes are still in the abdominal cavity, they already have a penis, prostate, seminal vesicles, and testes. Girls have noticeable labia, a clitoris, a vagina, a uterus, fallopian tubes, and ovaries.
The baby's body is formed, though the head might not look that large yet. Their upper and lower extremities are evenly developed, and the ratio of the lengths of the individual parts is correct. The phalanges (bones) of the fingers and toes are formed, and they have developed a fingerprint pattern.
With the growth and development of the muscular system, the baby's movements become more distinct. Under their influence, the cardiovascular system develops and the heart begins to pump more blood.
Sweat glands and a subcutaneous fat layer form in the skin, which will maintain thermoregulation when the baby is born.
If you are expecting twins
At this time, you will begin to feel the babies moving! Yes, a little earlier than single pregnancy moms. After all, twins take up more space than one baby, and they have slightly less fetal water in their bags [2].
What can be seen on ultrasound
The ultrasound image shows the baby’s head from above and we can see the diameter of the head. A bright horizontal strip is visible, which divides the infant's brain into the right and left hemispheres, showing the formed bones of the skull.
