Three clues, one baby: guessed, likely, and proven
The idea behind the cue
Presumptive signs are subjective changes like amenorrhea and nausea. Probable signs are objective findings such as a positive pregnancy test or uterine enlargement. Positive signs directly confirm the fetus, such as ultrasound visualization or fetal heart tones.
