Typically, amnio is only done early in the pregnancy if there is significant concern for genetic abnormality. So, while a person can have amnio at 11 weeks, there is substantial risk. |
I think there is always a risk. Amino is not always done or offered. Some insurances will not pay for the procedure unless there is a possible problem with the pregnancy or the mother is a certain age (young, or older).
There are tons of links just google ..I was trying to point out that it can be done earlier than 20 weeks. Usually the results take 1 to 2 weeks.
Amniocentesis
"Amniocentesis is usually performed at 15 to 18 weeks gestation, although it can be done as early as 11 or 12 weeks."
