What Pregnancy Weight Gain Calculator does
This calculator estimates recommended weight gain schedules for pregnancy on a week-by-week basis. Users input their height, pre-pregnancy weight, and current gestational age to receive a visual timeline showing minimum and maximum weight ranges for each week, aligned with Institute of Medicine guidelines. The output helps expectant parents track progress against standard medical references and understand typical physiological changes during gestation. The tool is designed for individuals monitoring prenatal health or seeking a quick reference point during routine check-ups, though results are approximations and not a substitute for professional medical assessment.
