Multiple “no result” on NIPT

Mercedes

Has anyone on here received multiple “no result” on a NIPT and gone on to have a healthy baby?

I’m in the normal BMI range, and had my first test at 9 week, second at 11 weeks, third at 13 weeks. The last two had 6.4 fetal DNA (so high enough to get results), but for whatever reason I just keep getting told there is no result.
