The method that would be used for an abortion at 14 weeks is D&E. Here's information and a drawing of a 14-week fetus, from The Visible Embryo:
Fetus is more flexible with ability to move head, mouth, lips, arms, wrists, hands, legs, feet, and toes.
Heart pumps about twenty-five quarts of blood per day and increases to three hundred quarts per day by the time of delivery.
Respiratory and digestive system - breathing, swallowing and sucking - are more developed.
Limbs are well-developed and more defined with toenails beginning to grow from their nail beds.
The following women and girls died from abortions done at 14 weeks: "Alice" Roe, "Becky" Roe, K.B., Sharon Davis, Carole Schaner, "Amy" Roe, and Tanya Williamson.
"Margot" thought she was 14 weeks pregnant when she went for an abortion. It turned out she was 20 weeks pregnant.
