I am not sure. Are you hooked on the methadone? Or are u looking for methadone treatment? Sorry to pry, I only ask because methadone is slowly being replaced by suboxone, I think they only use methadone for indiviuals who abused heroin for a long time. If you haven't been addicted that long suboxone would problay be the best way to go. Either way, I hope you get the help u need, it's out there for you. Please talk to someone. lots of love.
You should talk to your doctor regarding your addiction because it makes a difference on the pregnancy follow up. There are pain doctors that do prescribe it and there are clinics as well. Your Obgyn might be able to guide you to the right professional.
All the best to you and your baby.
