ve always heard not to take it.
What kind of
stomach ache, where exactly is it? How far along are you? Maybe try
to eat a small, bland snack? (unbuttered toast/bread, crackers, etc).... If the pain is severe go to the hospital, if its just uncomfortable and you don't have any other symptoms (fever, sweating, vomiting, bleeding, heart racing, etc) then maybe wait till you can talk to a dr. or nurse that knows you're pregnant. Hope you get to feeling better.
