Morning sickness

Need a bit of advice... This morning when I first threw up i noticed it was just blood nothing else πŸ˜• Im currently 8 weeks pregnant so is this something I should be extremely worried about. I researched it and it said I've torn the lining of my oesophagus which is why there is blood and I rang the 111 number which they said the exact same thing. I'm drinking plenty of water to soothe my throat in case. What else could it be??
