Could my NIPT results be wrong?

I received my NIPT results last Friday my doctor called me with results and told me it’s a girl! I had a very strong feeling it was a boy and honestly still in disbelief that I’m having a little girl because that’s what I wanted deep down. Today I announced it to my family and they all believed it was a boy my aunt on the other hand started making some snarky comments saying she does not believe it’s a girl because blood work is inaccurate and ultrasound would convince her otherwise she then went as far as saying that since it’s a girl she will not like me and will favor her dad... like who even says that? She was giving me such bad vibes and I honestly don’t know why she seemed so bother if the baby is a girl the whole time after that she seemed upset or bothered I could feel her energy and I didn’t like it. Now it’s making me think that I’m getting my hopes up and that the results are wrong.. has NIPT results been accurate for you? Now I’m second guessing.
