I only started getting cramps on Saturday, and yes, I agree, they are scary at first! But now I just tell myself that my uterus (which is backwards anyway) has to do a lot of work so has to grow.

Oddly enough, I drank about a pint of water before my scan today (half a litre) and that made me feel really bad, so drinking lots of water might not help after all. Or at least, downing a pint might not help.
