Am I poisoned by formaldehyde?

Ok so I was doing a biology lab, and we were dissecting a fish. Me and my lab partners were scraping off the scales of the fish when some of the juices flung up and hit my lip. I immediately wiped it off and rubbed some germ x on it (I'm a germ freak). I don't really feel like bad I guess, but my hands are a little shaky, and my stomach feels really acidic...the dissection happened yesterday morning...Should I go to the emergency room or something?? Please answer this question right away!!!
