Someone explain to me what’s going on 😭

So it’s been on and off for a couple of days that I feel like I have the flu (I don’t ).

I’ve been vomiting constantly (worse that the first trimester- first trimester it was stomach acid this is actually food).... cold sweats, loose stool.... like my whole body feels like it’s got the flu but I don’t . I’m 34.5 weeks pregnant and no one in my family has made it past 38 weeks . My mom keeps telling me it’s what happened to her right before labor .

Someone help and explain this to me . I’m in my bed completely naked with cold wet towels on me and trying not to throw up again while shaking .
