Clinic mess up

Odessa
I am 20 years old 17 weeks pregnant. I go to a place called crusader clinic, I really like the place but there is a issue going on which I need to know what should I do. So I had a appointment one day in the lady tells me my urine came back positive for some type of pill used to basically get over a drug? Like heroin! She could obviously look at me in knew it was a mistake in said she will test the urine I left that day, so my last appointment I just had a new doctor brings it up in basically says there tests are always 100%, and starts telling me that's what they are here for (blah blah) even though the last urine from my previous appointment in the one from that day testes negative! Its like she didn't believe me. I hate pills, cannot even take them so I don't no where to go about this? Can they get dcfs involved?
