Stomach Bile Morning Sickness!!!!

So today I had a banana for breakfast and some water! Then later on I had half a can of cola (because I needed something fizzy). (I’m 10 weeks, 2 days pregnant). About 30 minutes after drinking that I threw up and this is what it looked like. Is this brown bile from the cola?? Of course me being the worrier I am, the internet says if your vomit is brown then it’s blood. So I just wanted to make sure that this color is from the cola.. right?? Sorry !! TMI PIC!!
