During the early stages of pregnancy, it's common for women to experience bloating and water retention, which can make them appear more pregnant than they actually are. This is often due to hormonal changes and increased blood flow in the body. Additionally, if you have a smaller frame or are usually a size 0-2 pants, it's possible that your abdominal muscles are less toned and may stretch more easily, causing your belly to protrude earlier in pregnancy.
However, it's important to note that every woman's body is unique and pregnancy experiences can vary greatly. Some women may start showing earlier than others due to factors such as genetics, muscle tone, and previous pregnancies.
If you're concerned about your appearance or have any other questions related to your pregnancy, it's always best to consult with your healthcare provider. They can provide personalized advice based on your specific situation and help address any concerns you may have.
