Understanding Pregnancy Length
- Full Term: A pregnancy lasting 37-40 weeks is considered full term. [Source: Health.ny.gov, https://www.health.ny.gov/community/pregnancy/why_is_40_weeks_so_important.htm]
- Preterm/Premature: Babies born before 37 weeks are considered preterm or premature. This is categorized further into extremely preterm (23-28 weeks) and moderately preterm (29-33 weeks). [Source: Health.ny.gov, https://www.health.ny.gov/community/pregnancy/why_is_40_weeks_so_important.htm]
While 40 weeks is the average, individual pregnancies can vary slightly. It's crucial to consult with your healthcare provider for personalized guidance.
