Need help

Hi so little storie time and want to know has anyone had similar experiences. I did 2 dna blood test at a clinic for fetal dna testing one at 8 weeks a clinic and one at 23 weeks at a clinic both results said boy but did my anatomy scan and they saw girl parts so they asked for another scan which they didn’t quite sure of the sex and asked a consult in genetics at my hospital near by. Turns out they see girl parts with no uterus but it’s the first time they’ve mentioned that to me but baby wasn’t in a very good position that day so was hard getting pictures. They suggested an amniocentesis to go further see if any abnormalities. Baby’s scan are all normal and for Down syndrome too, but they mentionned my baby could have and think it has CAIS ( complete androgen insensitivity syndrome) which would explain the xy in the blood test and ultrasound female parts. Any similar experiences ? Is it worth doing the amniocentesis? Should I rely on my blood tests?
