How about movement of the fetus?

Fetal movement, often referred to as "quickening," typically begins around 18 to 25 weeks of pregnancy. These movements can include kicks, rolls, and jabs as the fetus grows and becomes more active. Monitoring fetal movement is important, as a decrease in activity can indicate potential complications, prompting expectant mothers to consult their healthcare provider. Overall, regular movement is a sign of a healthy, developing fetus.
