Blood in vomit. 1st Trimester

My KKH appt is in 5 days time. I barely had vomitting series in my 1st Tri. About less than 5 times. In the 3 times that I vomitted, it was mostly liquid, acid and blood. The blood is like watery, fresh red color. Is this normal? Should I wait for my appt or should I go to A&E? #advicepls #pleasehelp
