I am 35 weeks pregnant. I have been smoking Marijuana to help with nausea and so I ll have enough of an appetite to eat (I ve lost wright through most of the pregnancy). Now I am trying to make sure neither myself or the baby test positive for thc when I have a c section 1 month from now. Last night i tried cranberry juice and started having the first intense contracations Ive had this entire pregnancy. Can drinking cranberry juice cause me to go into labor sooner? If not will I be able to flush myself and the baby in a month if I drink cranberry and lots of water? Thank you for your time
