Do I Need To Go To The Emergency Room After Vomiting Pink For The Second Time Following Food Poisoning?

Hi, yesterday I had food poisoning and vomitted. The vomit was normal colored at first, but then became pink the next few times (it was a total of 5 times). I feel good now, but do I need to go to the emergency room? I really don t have the money for medical debt, so I only want to go if I know FOR SURE that it s life threatening.
