Definitely!

From the second I saw the bfp with DD I *knew* without doubt that she was a girl. It's the weirdest thing. DH and I chose her name very early on and didn't have any trouble deciding on it. I had a few dreams very early on as well about a little girl standing in my mother's back yard.

With DS I also knew, not because I felt a strong "boy" feeling but he just felt so different to my DD. The pregnancy itself was very similar but the "feeling" I had about the baby in my belly just was different. We were told at 14 weeks that he was a girl and I never told a soul because I knew that he wasn't and that his "real" gender would be discovered at his 20wk scan...which it was
