Pregnancy weeks → months
Convert gestational weeks to an approximate month value and see the trimester.
Estimate, not a diagnosis. This tool gives an educational estimate based on the numbers you enter. It cannot account for your individual health history — consult a healthcare professional for anything clinical.
Notes
Months are approximate — different sources map weeks to months differently. We use 4.345 weeks per month for a simple, consistent conversion and show standard trimester boundaries.
