I only had bad cramps twice in my pregnancy (though I still have a long time to go!). I cramped terribly BEFORE I found out I was pregnant, around 2weeks. I was curled in a ball, trying to ease the pain. I had cramps again around 6 weeks, but I reckon those were because my uterus was expanding.
If yours are continuous and that bad, I think that maybe, as Wobbles said, you should take yourself to the emergency. It will ease your mind, and hopefully stop those terrible cramps!
