Should my doctor be able to tell if it's a boy or girl at 14weeks and 2 days ?

I'm having my anatomy scan at 21 weeks, so I'll find out then

I got my ultrasound did at 14 weeks told me it was a girl went back at 15 weeks to confirm and it’s still a girl

I was told at 15 weeks and its been confirmed twice since then it was a voy

I wouldn’t trust it that early. They told me my daughter was a boy at 16 weeks and wouldn’t do another ultrasound. So I thought I was having a boy my whole pregnancy. Didn’t know it was a girl until she popped out.
