Tips & Warnings
Avoid strenuous activity for 24 hours after the procedure.
Call the doctor if you experience cramping, vaginal bleeding or fluid leakage, or anything unusual with your baby after the amniocentesis.
15 to 20 percent of pregnancies result in miscarriage in the first trimester. Amniocentesis is done later in the pregnancy - usually the 16th week - and has no significant impact on causing a mother to miscarry.
If you have any questions or concerns, contact a physician or other healthcare professional before engaging in any activity related to health and diet. This information is not intended as a substitute for professional medical advice or treatment.
