Does anyone think the doctor could be wrong ?

Lais
I went to my 19 week sonogram appointment today and they were gonna tell me which sex the baby was going to be. I had a feeling that it was going to be a girl cause i have to boys already and this new pregnancy got me feeling nothing like i felt with the other 2 ( thats why I thought it was gonna be girl) but guess what i was wrong and now i cant stop crying and feeling bad about it. Do anyone think she could be wrong ? Cause look at the picture is weird btw the baby is facing down
