Frequently Asked Questions
- What if I'm gaining more or less than recommended?
- Small deviations are normal. Weight gain isn't linear â some weeks you'll gain more, others less. Consistently gaining well above or below the range may warrant a conversation with your healthcare provider. The guidelines are ranges, not strict targets.
- When does most pregnancy weight gain happen?
- Most weight gain occurs in the second and third trimesters. In the first trimester, 1-2 kg total is typical. After that, expect roughly 0.5 kg/week for normal-weight women. The rate varies by pre-pregnancy BMI.
