every time i've ever been they have tested me for pregnancy because of things like xrays and certain medications. they also need to know in case you need a blood transfusion or other specific procedures.
do they always check 4 pregnancy when u go to the er? second month w/o a period? but they said nothing 1 way or other? . i went to er 4 vomiting/severe headache. they gave me nausa pills said it was a virus.
