Morning sickness

St

I am 17 weeks pregnant and I am so miserable cause all I do it vomit and feel nauseous. My bump is huge and I haven’t put on any weight whatsoever. I’ve tried everything. I’ve had antisickness tablets from my GP, ginger tea, ginger biscuits, milk../you name it I’ve tried it. I really am at my wits end. I’ve had my urine dipped and there ketones in it every time but Nothing is being done about it. I can’t cope with this any longer
