So I'm 37+5. I've had all the usual (diarrhoea, nausea, back ache, groin pain and cramps) for weeks now. But since last night my back is in agony and no position is comfortable. It's constant with the occasional really deep feeling ache (hard to describe). My right side keeps cramping and tightening like a stitch and starting to feel a bit sick. My stomach is solid but has been quite solid throughout. should I be getting checked out?!
