Good evening. Girls, could you share who did amniocentesis?

Good evening. Girls, could you share who did amniocentesis? How was it, were there any complications? Where did they do it? I saw a geneticist today, nothing normal was explained, scared me with Down syndrome, brought me to a panic attack. I am 35 years old, in my family and husband's family everything is fine, we have an older child, everything is normal. My blood test, ultrasound and age show 1:156 Now I'm confused about agreeing to this procedure, to give blood for NIPT or everything is fine. A friend says that doctors are ordered to prescribe this puncture after 35 years.
