Weeks 36–40+: Weekly appointments leading up to delivery.
Key Local Milestones & Resources
Choosing a Delivery Location: Most local OB/GYN practices require choosing your preferred hospital (such as the Hospital of the University of Pennsylvania, Pennsylvania Hospital, or Jefferson Einstein) by the end of the first trimester to align your care team.
First-Time Parent Programs: Philadelphia residents have access to community-based prenatal support, including the Maternal, Child, and Family Health (MCFH) services provided by the Philadelphia Department of Public Health, which offers home visiting programs and doula support connections.
