Hello, Welcome to Health Care Magic
I can understand your concern. Cord Blood and urine tests for drugs in new born are used commonly these days to find out drug use during pregnancy. These tests are rapid tests and are likely to come false negative with passage of time. Urine tests come positive for about a week of use. Blood tests come positive for a maximum of 4 weeks. You have used the drug about 7 weeks back so chances of the test to come positive are very unlikely. So no need to worry.
Thanks, Hope this helps you, if you have more doubts you can ask again
