Aww hun, your pg, your cramps might be a bit different or unusual than normal AF cramps.
Do you have any bleeding, or any "unusual tissues passing"?? I know that I always thought that if you are pg your CM is suppose to be minimal, but with this pg it was not. *TMI* I had a slight watery discharge, more that I would normaly have, but it was clear.

Like the girls said, if you are still worried .. let the dr do some bt's and put your mind at ease.

Hun, by fretting you are going to work yourself into some very tight knots. Take a deep breath and TRY and relax, ok??
