Calculadora de Gravidez: Data Provável do Parto e Trimestres
Calculadora de Gravidez: Data Provável do Parto e Trimestres
Esta ferramenta funciona 100% do lado do cliente. Seus dados biométricos, parâmetros de saúde e datas nunca são transmitidos a servidores remotos.
Fórmula e Método de Cálculo
Data provável do parto (DPP) = Data da DUM + 7 dias - 3 meses + 1 ano
Naegele's rule is the global obstetric standard. It assumes a standard 28-day menstrual cycle and computes a standard 280-day (40 week) human gestation period.
Melhores Práticas e Dicas
- Adjust for Cycle Length: Naegele's rule assumes a 28-day cycle. If a patient has a highly regular 35-day cycle, ovulation occurs later, and the Estimated Due Date must be manually pushed back by 7 days to remain accurate.
- Understand the Conception Paradox: 'Week 1' of pregnancy occurs before conception actually happens. Gestation is measured from the LMP, meaning when a positive test occurs at '4 weeks', the embryo has only existed for roughly 2 weeks.
- Prepare for the Window, Not the Day: Only 4% of babies are born exactly on their calculated EDD. Obstetricians consider any delivery between 37 weeks and 42 weeks to be a normal, full-term birth.
