4 weeks ago I had a scan in which the tech said she would guess the baby to be a boy, but was unsure. Yesterday I had another scan with a different tech, who asked what the other tech said and then said looks boyish, but she 'certainly wouldnt give a money back guarantee'.... not that it matters what gender our bub is, but what would you think??? Do they just say that incase they are wrong? She showed us his ?willy, but it looked nothing like my other boys, in fact I could barely see anything. When she looked under the spine it was round, nothing poking out. My husband is convinced its a girl.... Safe to buy blue????
