tmi blood in vomit

So I know I need to ask a dr but I don't go till Thursday and I don't want to go to urgent care unless really needed. I've had pretty bad morning sickness and for about he past week when ever I vomit there is blood and when I spit afterwards for about an hour it has blood in it. I'm pretty sure it's coming from my throat and it's not a huge amount... But I've never had this before. Not even with my first pregnancy where I was extremely sick. Anyone have this happen?
