Frequently Asked Questions
How much weight should I gain during pregnancy?
Weight gain recommendations depend on your pre-pregnancy BMI. Generally, women with normal BMI should gain 25-35 pounds, while underweight women may need 28-40 pounds, and overweight women should aim for 15-25 pounds. Our calculator provides personalized recommendations based on your specific situation.

What if I'm gaining weight too quickly or slowly?
If your weight gain is significantly above or below recommendations, consult your healthcare provider immediately. They can assess your individual situation and provide personalized guidance. Sudden changes in weight gain patterns may indicate underlying health issues that require medical attention.
