You had an amniocentesis. This is a prenatal test. It helps you learn whether a fetus has certain genetic conditions. It can also help find certain neural tube defects, check for an infection of the amniotic fluid, or check the fetus's lung development. The test is most often done between the 15th and 20th week of pregnancy.

• Limit your activity for 24 to 48 hours after the procedure.
• Know the risks involved with amniocentesis. This can help you recognize if you are having complications. Make sure you understand the following risks:
  • Loss of blood
  • Infection
  • Harm to the baby from the needle
  • Harm to the placenta or umbilical cord from the needle
  • Premature breaking of the amniotic sac
  • Premature labor or contractions
  • Miscarriage. (The risk of miscarriage is very low.)
• Don't be alarmed if you have some brief, mild cramping. This is normal.

Make a follow-up appointment with your doctor.

Contact your doctor right away if you have any of the following:

• Fever above 100.4°F ° (38°C) or chills
• Bright red vaginal bleeding or vaginal discharge that smells bad
• Contractions or severe cramping
• Liquid vaginal discharge that doesn't stop
• Redness or swelling where your doctor inserted the needle
• Decreased movement of the baby if the amniocentesis is done late in pregnancy
