Get startedFrequently Asked Questions
How much weight should I gain during pregnancy?
Recommended pregnancy weight gain depends on your pre-pregnancy BMI. The Institute of Medicine (IOM) guidelines suggest 25-35 lbs for normal weight, 28-40 lbs for underweight, 15-25 lbs for overweight, and 11-20 lbs for obese individuals. The Pregnancy Weight Gain Calculator provides personalized guidance based on your starting weight and current week.
How accurate are due date calculators?
Due date calculators based on your last menstrual period (LMP) are accurate to within about two weeks. Only about 5% of babies are born on their exact due date, but roughly 80% arrive within two weeks of the estimated date. Using conception or IVF transfer dates can provide a more precise estimate.
When should I start tracking pregnancy weight gain?
Begin tracking from your first prenatal visit, typically around 8-12 weeks. During the first trimester, weight gain is minimal (1-4 lbs total). Most gain occurs in the second and third trimesters at a steady weekly rate that varies by your pre-pregnancy BMI category.
Can I use these calculators as a substitute for prenatal care?
No. These calculators are educational tools that provide general estimates based on published clinical guidelines. They are not a substitute for regular prenatal checkups with your healthcare provider, who can account for your individual medical history and pregnancy circumstances.
