I have always wondered why pregnancy guides never mention cramping. Not to lull women into a false sense of security but to help them recognise "normal" cramping..
I tip-toed practically everywhere with my first bubby. I was utterly terrified of every new cramp. Actually the only reason I did a pregnancy test with DD1 was because I had such strong period pains, they had been going for a week or so and I realised I was well overdue!
