I'm 33 weeks and have just had horrible belly and back pains and felt really sick. Made me break into a sweat and then I couldn't see anything or hear properly as if I were about to pass out and then got the shakes really bad like I couldn't warm up! Also have had an urge to poo (sorry tmi!) quite a lot since then. Pains have stopped now, my belly just goes tight every now and then so feels a bit uncomfortable at the sides of my bump and in my back. Any idea what this could be as obviously still have another 7 weeks to go!
