If your vomiting blood clots u need to go and a and E now. It can be caused by stomach ulcers or a tear in your stomach lining, but it could also be a tiny cut because your throwing up but rule of thumb is if blood go check it checked out so u know it’s not anything emergency
If your not keeping liquids down call your GP or 111, it could be HG. I’ve been struggling for 3+ weeks with it now and had to be admitted to hospital for IV Drip. They also have great deal of information on what to eat and what not to eat. Hope that helps
@Ashley thank you so much 🤍 just worrying and panicking
