During the first trimester, a fetus grows from a tiny cluster of cells to about 3 inches in length and weighs roughly 0.5 ounces by the end of week 12. By the beginning of the second trimester, the fetus typically measures around 4 to 5 inches long and weighs about 1 ounce. Throughout the second trimester, growth accelerates significantly, with the fetus reaching approximately 14 inches and weighing around 2 pounds by the end of week 27. This growth marks a substantial increase in size and development as the fetus prepares for birth.
