I've been having pressure in my lower tummy and the rest of my tummy hardens. It is not painful yet but very uncomfortable. I had a show yday and have had period pains on and off for about a week that have gotten worse and stronger this weekend. Is this BH or maybe the beginnings of labour? I've been sick twice today and had a tummy bug today which I am getting over. (Lots of pain and diarrhoea, thought it was labour but I'm feeling better now). Now I just have the pressure and tightening in my tummy.
