Answer:
amniocentesis.
Step-by-step explanation:
Amniocentesis is a medical procedure performed to obtain a sample of amniotic fluid (the fluid from the bag that bathes the fetus). The procedure is performed using an ultrasound device to guide a needle through the maternal abdomen into the amniotic cavity. When the needle reaches the amniotic cavity, about 20 ml of aspiration fluid is aspirated.
Katrina probably went through an amniocentesis process, so she felt uncomfortable with the needle in her abdomen.
