NIPT results but no gender info 😭

So I got my NIPT blood test report and everything is fine. But I haven’t got to know the gender of the baby. I checked with my doc that I mentioned that I would like to know the gender too and she said I’m so SORRY, I misunderstood your question :( with NIPT you only got to know the gender if you are 35 yrs or older. I’m really pissed right now and she said wait for 20 weeks scan. 😟

Ladies please share what else I can go for, to know the gender of the baby. I’m 13w2d today.

Also in my 12w NT screening, technician said it’s boy but not sure. I would like to be 100% sure.

Plz help.
