Hello! I Had The NIPT Test Which Came Back Negative

Hello! I had the NIPT test which came back negative and my midwife assured me baby was fine and we are having a boy! Then just two days ago I get a call saying my IPT test came back positive! I'm freaking out! I thought the NIPT overruled the IPS but also read that the IPS can text for things that NIPT cannot. Should I be worried?
