Explanation: The equation calculates total weight gain by adding the base weight to the product of month number and monthly gain rate.
Details: Monitoring weight gain during pregnancy is essential for ensuring maternal and fetal health, identifying potential complications, and maintaining optimal nutrition throughout gestation.

Q3: When should I be concerned about weight gain?
A: Consult your healthcare provider if you gain more than 3 kg/month, or if you experience sudden weight changes or inadequate gain.
Q4: Are there factors that affect pregnancy weight gain?
