Do you have messages in your "Action Center" that state that an item is overdue? It may look similar to the image below.
These items are called health maintenance reminders. These items are generated based on your chart at your medical practice. A lot of times, these items may not be overdue and if that's the case, you can just ignore it. Right now, there is not a way to remove these from your account. The best thing to do now would be to ignore them.
