Once a sperm cell and an egg cell join, the fertilized egg begins to grow inside the woman’s uterus. During pregnancy the female body becomes a complete support system for the unborn baby.
It takes almost nine months for the fertilized egg to become a fully formed baby. Throughout this time, the uterus provides protection and warmth. As the baby develops, the uterus stretches until it is larger than any other organ in the body. The growing foetus shows in the pregnant woman’s “bump” at the front of her abdomen.
Your baby will change a lot throughout a typical pregnancy. This time is divided into three stages, called trimesters. Each trimester is a set of about three months. Your healthcare provider will probably talk to you about your baby’s development in terms of weeks. So, if you are three months pregnancy, you are about 12 weeks.
