I Am 29 Weeks Pregnant And Out Of Town. It's

I am 29 weeks pregnant and out of town. It's been really cold, windy and rainy since yesterday; I also ate a few pieces(3-4) of raw salmon sashimi at a reputable restaurant, but 2-3 hours later I started feeling sick and went to the puke everything out, then my nose started bleeding; my stomach also feels really tight like I ate too kuch(2-3 hrs ago). Do I need to go to the ER? I feel a tiny bit better after drinking hot water with ginger
