For your pre-pregnancy weight and being pregnant with twins, you should aim for a weight gain of 20-30 lbs by 20 weeks, 30-46 lbs by 28 weeks, for a total of 40-56 lbs by 38 weeks, which is term for twins. This pattern and amount of weight gain is associated with the best growth for twins and the longest length of gestation. If you do not make the 20-week goal, then try to meet the 28-week goal. Beyond 28 weeks, your weight gain will have much less influence on your babies' growth and the length of the pregnancy. You have gained 15 pounds by 14 weeks, which is right on target!
