Prenatal care involves regular checkups during pregnancy to monitor the health of the mother and baby. Checkups include a physical exam, ultrasound, and lab tests. They allow doctors to monitor weight gain, check fetal growth and heart rate, test for conditions, and identify potential complications. Regular prenatal care is important for having a healthy pregnancy and delivery. Reasons a pregnant woman may not get care include lack of awareness of the importance of checkups and barriers to accessing medical care.
