It is unlikely to have a big baby bump at just 2 months pregnant, especially if you had a small figure before. During the early stages of pregnancy, the uterus is still growing and the baby is very small. However, every woman's body is different and some may show earlier than others. It is important to note that having a large baby bump does not necessarily mean you are carrying twins. The size of your bump can be influenced by factors such as your body type, muscle tone, and the position of the baby. If you suspect you might be carrying twins or have any concerns about your pregnancy, it is best to consult with your healthcare provider for an accurate assessment. They can perform ultrasounds or other tests to determine the number of babies you are carrying and ensure everything is progressing normally.
