Which term describes the symptoms experienced by a woman that suggest she may be pregnant, such as nausea and breast bloating?

The term that describes the symptoms experienced by a woman that suggest she may be pregnant, such as nausea and breast bloating, is "presumptive signs." These signs are subjective indications reported by the woman and are not definitive proof of pregnancy. Symptoms like morning sickness, breast tenderness, and missed periods are common examples of presumptive signs, as they can be caused by other factors aside from pregnancy.

In contrast, the other terms refer to different levels of evidence regarding pregnancy. Probable signs are those that a healthcare provider might observe during an examination, like a positive pregnancy test or the enlargement of the uterus. Positive signs are definitive indicators of pregnancy, such as ultrasound visualization of a fetus or the detection of fetal heart tones. Possible signs are not a commonly used term in medical language but may imply any indication that pregnancy could be possible without being specific. Therefore, presumptive signs accurately capture the subjective nature of early pregnancy symptoms experienced by women.
