Oops, i accidentally just drank some raw unpasturized juice and i may be pregnant. what should i look out for?

Unpasturized juice: You could possibly develop vomiting or diarrrhea.

Nothing: I don't think there is anything to do about that. Drinking unpasteurized juice is like drinking freshly squeezed juice. Unless the fruit is know to be contaminated, then there is really nothing to do.

Gastroenteritis: Look initially for things like diarrhea, nausea, vomitting, fever, blood in the stool.

GI distress: From a reputable company it shoouldn't matter. Pasteruizing cooks the drink thereby killing potential bacterial contaminants like e coli and salmonella most of them cause nausea, vomitting, diarrhea to start the clinical course after which there can be further complications.
