In humans - 9 months.
An embryo typically develops a brain, heart, eyes, and legs within the first two months of pregnancy. By the end of the second month, these organs and structures are usually present and continue to develop throughout the rest of the pregnancy.
The embryo develops in the uterus of the mother.
The embryo of a human develops in the uterus of the female body. The uterus provides a protective and nourishing environment for the embryo to grow and develop into a fetus.
The first system to form in a human embryo is the nervous system. The neural tube, which will develop into the brain and spinal cord, is one of the earliest structures to develop in the developing embryo.
An embryo is not always stimulated to develop into a female. The presence of the Y chromosome leads to the development of a male embryo through the expression of genes that promote male characteristics. In the absence of the Y chromosome, the default pathway is for the embryo to develop into a female.

The same way that a human embryo or any other mammalian embryo does.
The heart begins to beat at the end of 3 weeks. Our 'reptilian brain' develops within the first two months, but our conscious thought does not develop until six months into the pregnancy.

If there was an actual embryo, it was not a false pregnancy.
The babies (embryo) heart starts to beat at about 4 weeks.

During the first two months of pregnancy, the embryo undergoes rapid cell division and begins to develop major organs and structures, including the brain, spinal cord, heart, and limbs. By the end of the second month, the embryo is referred to as a fetus, and its basic body plan is established.
