Disclosed herein is a system and method implementing a software-based method for detecting or confirming the detection of occlusions in the fluid path of an automatic drug delivery system. The invention uses real time glucose readings from a continuous glucose monitor in collaboration with past insulin delivery history and user indications of ingestion of carbohydrates, to determine cases where the user's glucose concentration is not being sufficiently impacted by the expected insulin delivery, which may indicate a significant pump site issue.
