Extreme nausea

I’m 8 1/2 weeks and started yesterday afternoon I have been vomiting about 5 x an hour. Very mild morning sickness before this point. Should I go to hospital or just ride it out? Not sure what’s going on or why I all of a sudden started vomiting so much. At what point would I need to go to the hospital for at least fluids and is there anything else they can even do? I also have diarrhea. Even though there is not much left of anything to come out at this point.
