When are most women likely to feel fetal movement for the first time?

Fetal movement, often referred to as "quickening," is typically first perceived by women during the second trimester of pregnancy. Most women begin to feel these movements between 16 to 20 weeks of gestation. This timing aligns with the development and growth of the fetus, where it becomes large enough and active enough for the mother to notice increased movement.

By around 16 weeks, the fetus is generally of sufficient size, and its movements are becoming stronger and more coordinated. This is when first-time mothers may notice the gentle fluttering sensations. Subsequent pregnancies may result in earlier awareness of fetal movements because mothers are more familiar with the sensations associated with pregnancy.

While some women may report feeling movements slightly earlier than 16 weeks, it's more commonly recognized as starting within this 16 to 20-week range. Therefore, the choice that corresponds to this timeframe is the most accurate.
