Final answer:
Presumptive signs of pregnancy are subjective symptoms experienced by an individual which could suggest the possibility of pregnancy but are not confirmed indicators, such as missed periods and morning sickness. They are distinguishable from other signs like a positive pregnancy test or Chadwick's sign, which are more objective.
Step-by-step explanation:
Presumptive Signs of Pregnancy
The question pertains to the subjective signs or symptoms of pregnancy, which are typically known as presumptive signs. Presumptive signs are not confirmed indicators of a pregnancy, but rather symptoms experienced by the individual, which might suggest the possibility of being pregnant. These signs include:
- Missed menstrual period: One of the earliest signs of pregnancy.
- Tender nipple area and breast changes.
- Increased appetite and frequency in urination.
- Nausea and vomiting, often termed as "morning sickness."
- Giddiness and breathlessness on exertion could be an indicator.
- Some individuals might experience a sensation known as quickening, which occurs when the mother starts to feel the fetus's movements.
The other signs mentioned in the question such as a positive pregnancy test, Chadwick's sign (discoloration of the vagina and cervix), and Braxton Hicks contractions are considered objective or probable signs because they can be observed or measured by someone other than the pregnant individual.
