Most women will require some form of general obstetric and antenatal care during their pregnancies. This type of care usually begins in the early stages of pregnancy, and continues until after the baby is born (postnatal). Some common services offered as part of general obstetric and antenatal care include ultrasounds, blood tests, and routine check-ups. It is important for pregnant women to seek out these services to ensure that they are healthy and on track for a safe delivery.
