Find out what you should expect with amniocentesis
An ultrasound is performed during the procedure so that the needle may be guided into the fluid without poking the baby. With use of the ultrasound, it is unlikely that the baby would be poked with the needle, but in the event that this does occur, it generally does not cause any serious harm.
There is generally no anesthesia needed during an amniocentesis, as most women only experience the sensation of the needle poke and then some menstrual-like cramps as the needle passes into the uterus.
This prenatal test usually only takes five to ten minutes. After the procedure, you can expect to have some mild cramping. Some women will have a small amount of vaginal bleeding or vaginal leakage of amniotic fluid.
Amniocentesis can result in leakage of amniotic fluid, infection and other complications. These complications are thankfully rare and generally occur in less than 0.5 percent of all amniocentesis procedures.
You should avoid strenuous activity or intercourse on the day of the procedure. In general, you should be up to your normal activity a day after the amnio. You should contact your doctor if you experience heavy bleeding or large loss of fluid, severe cramping or a fever.
