I am pregnant with #2, but my first was a boy and I did have GD for a bit. I was absolutely convinced that he was a she and when they told me it was a boy at u/s, I cried. I cried on the phone with my mom after I left the doc's office too. I knew I wanted a girl and I had the strongest feeling, "intuition" if you will, that it was a girl. When I found out it wasn't I felt as if my "mother's intuition" was broken. Obviously, I love my DS with everything I am and couldn't imagine him any other way.
BUT, I will also say that the GD from my pg with him has carried into this one. I have been so hesitant to even allow myself to think what I really "intuitively" think this baby is. Only because I don't want the disappointment again, but if I am having another boy, I think I will go through it again. Maybe not quite as bad, but I believe I will.
Best of luck to you.
