How much does your belly grow in the first trimester of pregnancy?

During the first trimester of pregnancy, most women do not experience significant belly growth, as the uterus is still relatively small and mostly contained within the pelvis. However, some may notice slight bloating or a change in their waistline due to hormonal changes. Typically, noticeable belly growth begins in the second trimester. Individual experiences may vary based on factors such as body type and whether it's a first pregnancy.
