What does the term 'quickening' refer to in pregnancy?

The term 'quickening' specifically refers to the first time a pregnant woman perceives fetal movements. This sensation typically occurs between 16 and 25 weeks of gestation, marking an important milestone in the pregnancy as it signifies that the fetus is developing and becoming more active. The ability for the mother to feel these movements fosters a stronger connection with the developing fetus and is often a sign of its health and well-being.

The other options, while relevant to pregnancy, describe different stages or aspects. The moment of conception occurs well before any signs of fetal movement can be felt. Braxton Hicks contractions, which are irregular and often painless contractions that can occur throughout the second and third trimesters, are not related to the feeling of fetal movement. The term viability refers to the point in pregnancy when the fetus has a reasonable chance of surviving outside of the womb, typically around 24 weeks, but this does not coincide with the sensation of movement known as quickening.
