Gestational diabetes drug recall... took it for a week then give gave birth 32 weeks into pregnancy?

Not necesarily, it sounds like someone just grabbed the wrong box of inserts to go with the medication, the medication itself isn'tin question. To be sure, take the medication back to Walgreens and ask over the counter if the wrong medication was prescribed. My guess is that it's fine, not at fault for the premature delivery of your twins and very unlikely to cause long term ill effects.
