Thanks for taking the time to reply girls.

kts - thank you for your kind words, they really do mean a lot

Your fellow BB members are hurting, the TV and radio are full of bad news and sadness, it would not be at all suprising if it is affecting you, even if it's only on a subconscious level. Add to the being preggy and it is a recipe for stress and a big black hole.
You may be right about that Heather, it may explain it a little, thank you.
