Any complications: in your first three pregnancies? You have an increased risk of Down syndrome, approximately 1%,because of maternal age. However you may ask for a fetal DNA analysis in your blood from 10 weeks on which can be sent overnight to 1 of 4 laboratories in the with results in 4 to 7 days. The risk of a false positive is less than 1 in 1000, and should be confirmed by amniocentesis or CVS.
