Mild cramping, bruising and all that is normal and caused by the change in hormones and stretching :-)
Thank you for your reply. I'm going tomorrow so in going to ask then. I will post what im told :)
From my experience only I got a bruise like line when my stomach started to stretch but I was a few months pregnant at the time and I think most woman get that although that's not much help maybe you knocked your self and not realized but if your worried speak to a midwife to put your mind at rest x
