AH man! after reading the title, I had a very witty comment. But, I guess that would be inappropiate after reading the text. I'm such a dirty girl! Sorry for your discomfort.
I have this too.. Normally when I wake up in the morning. It feels like someone has kicked me down there. I did not have this with my DD #1 and I remember she was really high up. I am guessing it's probably the baby putting a lot of pressure down there.
