Is there a safe way to detox my system in the last month of pregnancy?

Shouldn't need to: What do you have in your system to detox? There isn't any "detox-medication" available by prescription because there is no such thing. Be best/healthiest way is to stop ingesting "toxic substances" if you are doing so, eat well, exercises and the body will heal/detox itself. Don't put chemicals in your body if you don't need to. Be good. Live well, live healthy. Congrats on the pregnancy. Good luc.
