Twin Pregnancy Due Date Calculator
Twin and higher-order multiple pregnancies are often monitored more closely and may plan for birth earlier than singleton pregnancies — many guidelines cite approximately 37 weeks as a common planning horizon for uncomplicated dichorionic twins, with timing individualized by your MFM or OB team. This calculator still uses standard LMP-to-40-week math for the classic estimated due date; use the results alongside your provider's twin-specific schedule for cervical length, growth scans, and delivery planning.
