Throwing up blood ???

Brittany

So I’m 13 weeks and 5 days. Last night I had subway for dinner. I have been throwing up bad since the night before. Well last night I threw up and there was blood in my throw up. Not too much but definitely a good noticeable amount. I’ve been feeling really crampy for a couple of days. My fiancé said it could be from throwing up so much. I have no clue what it could be but it only happened once. Has anyone experienced this or have any suggestions on what it could be ?
