I went to the er for same thing if you throw up blood and its darker it means its coming from your stomach if its red its your throat... when you throw up you can get what are called Mallory Weiss tears in your throat and that makes blood come out with your vomit the Dr told me if you barf normal then get blood its normal but if you out of nowhere barf and its blood then come in
I did that when I had a kidney infection go to the er now it can send you into labor
Could be blood from your throat due to stomach acid coming up. If it's a lot of blood then go in.
NO!!! Please go to er right away!
