5weeks 4 days. Been up three times already in the night with the runs and each time I lie down I feel horrendous. If I lie on my side, I feel pressure in my tummy and then I feel ill so have to move onto my back. I have a sore tummy which is a sick tummy, not a crampy tummy. Is this the start of the "morning sickness" that can happen anytime? My stomach is rumbling and gurgling. Or have I just eaten something that didn't agree.
