Some women worry about adding pounds when they are pregnant. Pregnancy is not the time to fret about putting on weight. It’s also not an excuse to eat too much, though. Most women need between 1,800 and 2,200 calories a day when they are not pregnant. Pregnant women need about 300 more calories.

Condition Before Getting Pregnant | Weight Gain (lbs)
