Pregnancy weight gain calc

How much weight you should gain during pregnancy depends on whether you were underweight, at a normal weight, overweight, or obese before you got pregnant (and whether you’re carrying twins or multiples).
Use this tool to find out which category you're in and get your target weight range for this pregnancy. If you tell us your week of pregnancy and current weight, we'll also show you if you're on track for ending up at a healthy weight.
