Q

Lasting about seven months, is the prenatal period between two months after conception and birth in typical pregnancies. At about 23 weeks after conception, midway through the fifth month, the fetus reaches the age of viability, when survival outside the uterus is possible if the brain and respiratory system are well enough developed.
