Wow need advice

So I’m currently looking for a better hospital I got blood work done at like 11 weeks my test results came back male baby I’m guessing bt my fetal fraction was low for the dna and screening came back negative or low risk bt I only seen this on line posted to my medical history so mind u they never called me with no results or nuthing bt wen I went back in said they was testing for somthing else and then she called me like two days later and said something came back abnormal bt start saying it’s just a screening not real diagnosis so I’m like wats the sex of the baby she said I’m guessing it’s saying boy I said soo are these results 100 so should I buy boy stuff my doctor saids no I’m I was upset she said just wait to 20 weeks scan bt how everybody kept telling me the blood is 100% she like no it’s not just wait and I’m like y are they doing my test twice what do y’all think need advice cause now I’m a lil stress like wats abnormal and is the sex of the baby wrong how Any advice
