Im 32 weeks and 2 days pregnant. I just recently stopped smoking weed a couple days ago. I know that makes me sound horrible, but I only did it to sleep and eat. The hospital drug tests me and the baby when he is born, and I could possibly lose him if we both fail. I was just wondering how long it would take to have clear urine and if there are any safe methods to cleaning my system of THC? I'm desperate. Thank you so much!
