Pregnancy Health Calculator: Track Your Journey Week by Week

A healthy pregnancy requires tracking multiple health metrics from conception through delivery, and our suite of pregnancy calculators helps you stay informed at every stage. Our due date calculator determines your estimated delivery date based on your last menstrual period or conception date, giving you a clear timeline for the 40-week journey ahead.

Recommended weight gain during pregnancy varies based on your pre-pregnancy BMI: 25 to 35 pounds for normal weight, 15 to 25 pounds for overweight, and 28 to 40 pounds for underweight women. Our pregnancy weight calculator tracks your gain against these guidelines week by week, alerting you if you are significantly above or below the recommended range.

Proper nutrition during pregnancy supports fetal development and maternal health. Calorie needs increase by approximately 340 calories per day in the second trimester and 450 in the third. Use our calorie calculator for adjusted intake targets, our water intake calculator to meet the increased hydration needs of pregnancy, and our ovulation calculator for family planning.
