I need help does anyone have experience with cps in Florida

Before i say anything please be as nice as possible. Before I got pregnant I was a heavy marijuana smoker when I found out I was pregnant at 5 weeks and 4 days I stopped completely. Then at 10 weeks I smoked only two times and I didn't smoke that much. I am worried that I will be tested positive at my next appointment in about a week and cps will get involved. I live in south Florida. I'm also concerned about them testing my baby's poop at birth and it testing positive. I've done at lot of research and I know the baby's poop doesn't start forming until 16-20 weeks but I'm still a little worried. I haven't smoked since and I don't plan on smoking again. Does anyone have experience with this or know anything about it?
