Why am I throwing everything up ? Will this harm the baby ?

No matter what I eat , it comes up . I ate some candy , I threw it up. I ate chips , I threw it up . I just had a slice of pizza , I threw it up . I had oranges this morning , I threw it up . I don’t have an appointment with my ob until November 4th . If I go to the emergency room , can I get prescribed some medicine for this ? I don’t have energy most of the day . Is there any remedies you guys know of ? I’m only about 8 weeks .
