Boy??? Helpppp

Ok! So I got a early gender I was supposed to be 14 weeks when I got it. Well, I finally got my dating scan from my doctor, because it kept being cancelled due to snow..and I just wanted to see my baby. So I didn't cancel with the gender.  I'm measuring 13 weeks 1 day. So when I got it done I was 12 weeks and 5 days. I'm wondering if the gender they gave (boy) would be accurate?  I have message them, they were very understanding and are looking back over pictures and might even have me come back in to take a peek. But it's driving me crazy. What do you think based on ultrasounds..
