Week 8 is still pretty early in your pregnancy, so you probably won't look too different. Some women may start to notice subtle changes in their body, like weight gain around their waists. However, most women only gain about five pounds in the first trimester, so weight gain should not be significant at this point. In fact, some women actually lose weight as a result of the nausea of morning sickness. Either way, you will probably start to feel a difference in your abdomen since your uterus is now the size of a grapefruit. By week 8, many women also notice that their breasts are becoming noticeably larger.
