If you are pregnant with more than one baby, you may experience problems during pregnancy. These potential problems could include high blood pressure, diabetes, anemia (low blood count), or too much or too little amniotic fluid (the fluid that surrounds the baby during a pregnancy). Too much amniotic fluid can be a problem because it can cause premature labor, while too little fluid can cause a problem with the baby’s development. You may need to stay in bed or the hospital for weeks before delivery. This is especially likely if you go into labor early. Also, you may have problems delivering your babies. There is a higher likelihood of undergoing a Cesarean section, which is when the babies are delivered through a surgical opening in your belly.
