Pregnancy can involve physical complications that require medical care to prevent maternal or neonatal death. Warning signs include bleeding, convulsions, swelling, severe headaches, prolonged labor over 12 hours, and broken waters during pregnancy. Women need regular prenatal care to monitor for these issues, as immediate treatment is necessary if any symptoms arise, since even brief delays can prove life-threatening. It is important to plan ahead for emergencies by having transportation arranged, saving money for medical costs, designating someone to assist at the hospital, and knowing a woman's blood type if she is anemic in case she requires a transfusion.
