Can your family have symptoms of pregnancy?

No, only women can be pregnant. Pregnancy is the state of carrying one or more offspring in the womb. It begins with fertilization, when a sperm cell from the father meets and penetrates an egg cell from the mother. The fertilized egg, or zygote, then divides and develops into an embryo and eventually a fetus. Pregnancy lasts for about 9 months in humans. During this time, the mother's body undergoes changes to support the growth and development of the fetus, such as an increase in hormone production, a growing uterus, and changes in the breasts.
