During weeks 17-20, quickening occurs, which is when the (d)<u> mother is able to feel the fetus move inside her womb.</u>
The period during which a fetus develops inside a woman's womb or uterus is known as pregnancy, it typically lasts about 40 weeks or just over 9 months in humans.
During the course of pregnancy, the fetus develops from being a single cell to a complete individual.
Quickening is the movement of the baby inside the mother’s womb at around 16-20 weeks of pregnancy. It assures the health and growth of the baby inside the uterus. A fetus that is growing well stimulates more quickening movements.
