My 20 week us was done by a student midwife and he seemed very under pressure and confused, he had a qualified midwife overlooking him but he seemed to make mistakes a lot and she had to pick him up on it and would take over.
Towards the end of the scan he asked if id like to know anything else and I said I would like to know the sex (by this time the midwife that was watching him had left) he asked if I had any gut feelings and I said I thought he was a boy because I just had a feeling. He briefly looked down and then brought the scanner back up and didn't show me anything just said "yeah I think your right, I saw something dangle so a boy"
Would you trust this? I don't know ever since that scan I have doubted it and have had dreams that I have a baby girl.
Here is the only scan photo I got that you might be able to see something in in terms of genitals
