when should i go to a hospital ?

it’s currently 3am where i am i have been vomiting since the day before around 12pm i cannot keep fluids or food down i’ll take 2 tiny sip of water then start to feel dizzy signaling i’m about to be sick it tastes like i’m throwing up a pill ..i have been become monitored for high bp and was giving a cuff when i took my bp yesterday it was 117/88 it’s usually in the 125-30’s. i don’t feel like i have a stomach bug i also do not feel like i’ve had a fever , i just suddenly feel sick when i eat or drink anything ! i am also 26 weeks pregnant i’m 19 , and just very worried that my daughter isn’t being supplied enough nutrients because i cannot eat or drink anything .. should i call an onsite OB or just go in ?
