One of my friends took a home pregnancy test when a guy friend said he thought she was preggo...freaked her out when the test she took came out POSITIVE.
Can You Tell a Woman is Pregnant Before She Knows It? - Page 3
I can just kind of "sense" another person there, but maybe they are further along than what you are talking about. I am almost almost ALWAYS right on gender though. It's that whole "other person" thing that either feels male or female to me. In fact, I just correctly called my college roommate's baby bump as a girl a week or so ago.
I also once had a dream about my best friend having a baby boy and a few hours later, my phone rang. It was friend calling to tell me that she was pregnant (I was the first to know- even before her DH because she wanted to tell him in person but had to tell someone right then). I responded with "Well, it's a boy." She wanted to know how I knew that. I told her I'd just had a dream about her having a boy. 9 months later, we joyously welcomed her beautiful baby boy to the world.
