Trisomy 18 positive NIPT

hello, I’m posting to try and get some sort of reassurance or miracle information that I haven’t already read. I am 25 years old and 14 weeks pregnant. I have had 3 scans all of which I have been told the baby is looking healthy with a strong heartbeat and the NT is measuring 2.1mm. I was offered screening tests which I accepted and did the blood test thinking everything would be totally normal. last week I got a phone call saying that the baby had a high chance of having trisomy 18, I was told it would be a 1 in 17 chance. We then opted to do the NIPT test which has come back saying high chance but have been given no statistics with this result. We are now booked in to get an amniocentesis which I am super anxious about. I’ve spent the past 2 days researching trisomy 18 and trying to find people who have false positive results for a little bit of hope. what a rollercoaster it has been so far and the wait until we get the test and results is going to be torture. Has anyone else had a similar experience?
