Calculadora de fecha probable de parto

Estimate based on 280 days from the last period, adjusted by cycle length minus 28. Gestational age uses this same cycle adjustment; in French it is expressed in weeks of amenorrhea (SA). Irregular cycles can make this estimate unreliable.

This does not confirm pregnancy or replace antenatal care. A dating ultrasound can refine the estimate; use the due date established by your clinician.
