I'm 37 weeks and feel like (sorry for horrible description...) I would if I were about to have a really heavy period. The tops of my legs ache and so does my stomach - there are no tightening and loosenings, just constant cramping then aching from the cramping. As well as this, my lady bits feel bruised and like I've been kicked repeatedly and I feel sick as a dog. Though baby seems to have moved so I can breathe again, hooray! Is this all normal or could it be a sign of a possible early birth?
