Does your belly button feel different during early pregnancy?

In the early stages of pregnancy, it is unlikely that there will be noticeable changes to the belly button itself. However, as the pregnancy progresses, the growing uterus will naturally cause the abdomen to expand and eventually cause the belly button to pop out or become flatter. Some pregnant individuals may experience these physical changes to the belly button as early as their second trimester, but typically this is a change more commonly observed in the third trimester when the baby bump becomes more pronounced.
