Hi everyone, so my 18 week was pretty obvious, we saw the penis and Dr said sorry it’s a boy (we wanted a girl), but I’ve zoomed in a bit and saw 3 lines on the penis. Also is attached where the gynae said the umbilical cord is on the tip of the penis. Has anyone been told boy and then few weeks later been told girl? Haven’t been after this scan though so don’t know.
