Need advice asap

I’m 8w2d pregnant and my morning sickness has been pretty bad. More so mostly nausea but sometimes it has been bad enough to make me vomit quite a few times here and there. I just got done vomiting a few moments ago and noticed that my vomit was tinged red. I don’t remember eating anything red. Could it be blood? Should I be worried? I have my first doctors appointment on Friday and I don’t think they can get me in any sooner.

I’m kind of freaking out because I didn’t eat anything red. Except for an apple but just the skin of the apple is red so I doubt that could tiny the contents of my stomach red.

Has anyone else vomited up a bit of red without eating anything red????
