Question: how much weight should i gain by week 16 pregnancy?
Answer: If you are in the healthy weight range before becoming pregnant (BMI 18.5-24.9), ideally you should gain between 11.5 kg and 16 kg: 1 to 1.5 kg in the first three months then 1.5 to 2 kg each month until you give birth. If you are above the healthy weight range, you should gain less.
