If you are carrying multiples or more, there are no set guidelines for pregnancy weight gain due to insufficient data. You should talk to your OB/GYN on how to gain the right weight.
When Do You Start Gaining Weight During Pregnancy ? You will start to gain weight during the first trimester (due to retained water), but that is minimal. In the first month of pregnancy, there is little or no weight gain as the baby is just a tiny ball of cells. In fact, you might lose weight due to morning sickness in the initial months. Most women put on about 1.6kg in the first trimester. During the second trimester, you will have the highest weight gain since your eating habits influence the baby’s weight. You will put around 0.5kg every week, totaling 5.5 to 6.4kg in that trimester. There will again be a considerable increase in weight during the third trimester, and it may slow down in the last month (due to food aversions or having an active baby). You will be gaining around 5kg in the last trimester. That is, normal weight gain during pregnancy should varies from 10 kg to 15 kg but again it depends on BMI ranges.
