No: I work in a cardiac cath lab and my nurse was pregnanat and wore a badge outside her lead apron. It received essentially zero radiation despite hours and hours of exposure. The key is the inverse square law. The radiation drops off very quickly as you move inches away from the source (the patient's bloodstream). You have had a negligible exposure - you get more on a sunny day!

Shouldn't: There is no good evidence that this exposure would cause any harm at all to the fetus. But always keep in mind that the spontaneous miscarriage rate is about 15%. The 30 minute exposure described would not increase this rate of miscarriage.

Not really: Diagnostic imaging radiation is very low and not likely to cause any problems with your pregnancy. Follow up with your ob/gyn as usual.
