## **Core Concept**
Quickening refers to the moment when a pregnant woman first feels the movements of her fetus. This phenomenon is an important milestone in pregnancy and can vary depending on factors such as the woman's body size, whether she has had previous pregnancies (multigravidas tend to recognize the sensation earlier), and the position of the placenta.

## **Why the Correct Answer is Right**
The correct answer, typically around 18-20 weeks of gestation, is considered the period when quickening can usually be felt. This timeframe can vary, but 18-20 weeks is a commonly cited range. The sensation of quickening is due to the fetus's movements becoming strong enough and frequent enough to be perceived by the mother. In first-time mothers (primigravidas), it might be felt a bit later, around 20 weeks, whereas in those who have been pregnant before (multigravidas), it might be recognized as early as 16-18 weeks.

## **Why Each Wrong Option is Incorrect**
- **Option A:** 10-12 weeks is generally too early for most women to feel quickening. While some women may report feeling movements this early, it is not the typical range.
- **Option B:** 14-16 weeks might be a bit early for primigravidas but can be within the range for multigravidas. However, it does not represent the broader, more general timeframe for quickening to be felt.
- **Option D:** 22-24 weeks is generally later than when most women first notice quickening. While there is a range, 18-20 weeks is more commonly cited.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the perception of quickening can be influenced by several factors, including parity (number of previous pregnancies), body size, and the presence of a placenta in the front of the uterus (which may cushion the fetal movements). A useful clinical correlation is that in multigravidas, quickening is often reported earlier than in primigravidas.

## **Correct Answer:** . 18-20 weeks
