i went for my 12 week scan,turns out i was 15 weeks and 4 days. mil went with me. she reckons she seen the boys bits. i thought it was a boy because the scan between this one and my daughters is completely different! anyone know good nub theories or some theories i can determine from the scan photo? I'm having the 20 week scan in a week and I'm so excited but anxious! ive got my my mind set on a boy and don't wanna be disappointed,not trying to sound ungrateful I'm so lucky and happy I'm pregnant!
