NIPT test?

Had it twice, first on my 13 weeks, second 16 weeks and both the result come as “high data noise” so there’s nothing to do since the result itself is unclear. And I don’t opt for another test anymore, I’m now 26 weeks & from the usg itself several doctors said that baby is very active, have a nose bone (which means he don’t have which kind of trisomy I forgot) and all the physical exam showing my boy is quite normal, but well, the simple truth for every pregnant woman out there is there are no 100% guarantees even from any tests or USG until the baby is born.
