How many months does it take for a fetus to be formed?

Patient's question:

No

Doctor's answer:

The first three months: The key period for fetal development, as cells divide to form a complete, tangible, but immature human.
The second three months: The fetus grows rapidly, increasing by about 5 cm each month, eventually developing facial expressions, the ability to swallow, hearing, and the ability to kick.
The last three months: In the final three months, the fetus gains weight rapidly, with an average birth weight of 3.4 kilograms.
