With my first I knew he was a boy from the minute I found out I was pg, and I was right. With my second I didn't know and had no real vibe either way. With my third I also didn't know. With this one I'm getting a boy vibe, but nothing like 'knowing' like with my first. Maybe I'm just expecting another boy after 3 I had no real vibe either way with this pg until I saw the u/s pic at 12 weeks and straight away I thought boy. no nub to see, I just thought boy, so we'll see ...
