There are other medications available for opiate detoxification such, as suboxone

), but because they are "Pregnancy Category C" medications, meaning they are known to cause harmful and possibly fatal birth defects on a fetus, the are not recommended for use in detoxifying pregnant women.
I wouldn't worry so much on testing
dirty for opiates when your baby comes.
