What is a high-risk pregnancy?
There is no one, formal definition of a high-risk pregnancy. Generally, a high-risk pregnancy means:
You or your baby is more likely to become ill or die than usual
Complications before or after delivery are more likely to occur than usual
Certain conditions, called risk factors, make a pregnancy high risk. Problems can happen during the pregnancy, during delivery, or in the weeks after delivery.
Doctors watch high-risk pregnancies very carefully
If your pregnancy is considered high risk, you may be sent to a special doctor, clinic, or hospital
