End of 8th week
At the end of 8 weeks, the length of the fetus is about 14-20 mm and you can already begin to distinguish its eyes, its ears, its mouth and nose. All parts of its body and organs are developing rapidly and the fetus has already started moving.

End of 12th week

At the end of 12 weeks, the length of the fetus is about 60 – 70 mm. At this stage, all parts and organs of its body are fully formatted. You cannot tell its sex yet, but you can hear very clearly the beating of its heart.

End of 16th week

At the end of 16 weeks, the length of the embryo has reached 10.4 to 11.6 centimeters. Its legs have been developed and the head is more erect than before. The nails also begun to be visible in its hands and feet, its head has some fluffy hair, and the ears are very close to their final position.

End of 20th week

End of 30th week

At the end of week 30, your baby is 38 cm long and fully developed. Its skin is smooth and rosy, and has started to develop subcutaneous fat which allows it to regulate the temperature of its body. It has also grown considerably now and there is not enough space to move comfortably.
