I went for my 20 week scan at 18 weeks 5 days

The doctor said the baby was in a bad position and she couldn’t see the gender. They told me to come back in 3 hours. When I came back, the baby had moved from the earlier position but still wasn’t in the best position. The baby was facing down this time (almost as if she was laying on her tummy with her face down) but this time the tech said she was able to see the gender! We had our reveal party and it’s a little baby girl!! We are sooo excited but now I am just wondering how accurate what she saw in between the legs was if the baby was facing down? Is there a chance she could have missed something because the baby was laying on its belly instead of it’s back?

Any expierence with this anyone?
