What is amniocentesis?

Amnio is a procedure: Amniocentesis is the procedure during which a long, slim needle is inserted through the prenant woman's abdominal and uterine walls and through the membranes of the amniotic sac, and fluid is aspirated/drawn into a syringe attached to that needle. Fluid can be studied for chromosomes (karyotype) or special genetic disorders, for infection, for lung maturity and for other conditions of baby or mom.

Amniotic fluid: Amniocentesis is a technique for obtaining amniotic fluid from the uterine cavity using a needle. It can be for both diagnostic and therapeutic purposes. It is most commonly used to evaluate fetal health (e.g., lung maturity, presence of infection...Etc.).

Wait for results: I presume you are undergoing amniocentesis for genetic testing. Take it easy for a day or so, your doctor will give you precautions to follow
