I went to the shops today and while I was standing at the checkout a random woman behind me told me 'it's a boy' and pointed at my belly...😐 A few weeks ago the same thing happened with another lady and it seems like before we found out most people thought boy too from the way I was carrying. I always thought that was an old wives tale but so many people have guessed right! This is me at 25 weeks... what do you think? Any truth to it?
