i would wait. he mc is your cleansing your toxins, which means they would be moving through your fetus. also, a developing fetus needs a wide variety of nutrients and vitamins and you don't want to deprive that and the lemonade drinks definitely don't have enough of everything for that. i also don't recommned doing the mc while breastfeeding because, again, you're releasing toxins and the breastmilk will have a large portion of that. just wait until after the baby is born, is done breastfeeding, and you have more time to cleanse your body.
