What type of pregnancy signs are amenorrhea and fetal movement classified as?

Amenorrhea and fetal movement are classified as presumptive pregnancy signs because they are physical indicators that a pregnancy may be occurring, but they are not definitive evidence of pregnancy.

Amenorrhea, or the absence of menstrual periods, is a common early sign of pregnancy due to hormonal changes, specifically the increase in human chorionic gonadotropin (hCG) levels. However, amenorrhea can also result from other factors such as stress, hormonal imbalances, or significant weight changes, which is why it is not considered a conclusive sign of pregnancy.

Fetal movement is another signals that can suggest pregnancy, typically felt by the mother around 16 to 25 weeks; however, it can occasionally be perceived in non-pregnant states due to other abdominal sensations, thus reinforcing its status as a presumptive indicator rather than a definitive one.

Positive pregnancy signs, such as the detection of fetal heart tones via ultrasound or the visual confirmation of a gestational sac, provide definitive evidence of pregnancy. Negative pregnancy signs typically refer to circumstances or symptoms that suggest the absence of a pregnancy. Diagnostic signs are medically confirmed indicators that confirm a pregnancy's existence.

As a result, the classification of amenorrhea and fetal movement as presumptive pregnancy signs
