Hegar's sign is classified as which type of sign of pregnancy?

1. Positive sign of pregnancy

2. Probable sign of pregnancy

3. Presumptive sign of pregnancy

4. Problem in pregnancy

The correct answer is: Probable sign of pregnancy

Hegar's sign is classified as a probable sign of pregnancy because it refers to the softening of the lower segment of the uterus, which can be detected during a pelvic examination. This physical change typically occurs around six to eight weeks of gestation and is often one of the first markers that healthcare providers look for when assessing a woman for pregnancy. Probable signs are indicators that can provide evidence of pregnancy but can also be caused by other factors, making them not definitive. Understanding the distinction between different types of signs is important in clinical practice. Positive signs are those that can only be attributed to a developing fetus, such as fetal heartbeat detected via ultrasound or fetal movement felt by the examiner. Presumptive signs are subjective symptoms that the woman experiences, such as nausea or missed periods, which may not solely indicate pregnancy. Recognizing Hegar's sign as a probable indicator helps in making an informed assessment while also acknowledging that further confirmation through positive signs may be necessary for a definitive diagnosis.
