| Goodell's Sign | Softening of the cervix. |

| Striae | Purplish stretch marks, that slowly turn silver after childbirth, may develop as pregnancy progresses. |
| Colostrum | An antibody-rich, yellow secretion, may be expressed manually by the 12th week and may leak from the breasts during the last trimester. |
