Could your belly change at week 5 of pregnancy?

It is unlikely that your belly would change noticeably at week 5 of pregnancy. At this stage, the embryo is still very small and is typically no bigger than a grain of rice. The uterus, which is the organ that houses the embryo, is also still small and is located deep within the pelvis. As such, it is not likely to cause any visible changes to your belly. However, some women may experience slight bloating or changes in their waistline at this stage, but these changes are typically subtle and may not be noticeable to others.
