12 yrs ago i was really addicted to heroin, i found out at 4mths that i was pregnant, since cold turkey was not an option because of the risk of losing my baby, i was put on
methadone, but now they have something safer which is suboxone or
in your case maybe subutex. My doctor says that he has had much success with treating pregnant women with it. i guess you really have to weight out your options, being that you still have pain issues.
