Okay so these are my 16+5 week potty shots, where I was told boy (I screenshot these from a video) 2 look boy but but told that one (3 lines) look like a definite girl and I'm starting to question it, I've had my 20 weeks scan since, they didnt mention it as I told them I knew he was a boy, but not I'm thinking theres a chance it could be the umbilical cord... are there any experts that could give their opinion?? Should I be buying neutral just incase?
