Navicular Undisplaced Fracture Query.

Hi Sir/Madam, Iam having Navicular Hairline Fracture almost 35 days back, but I got to know about fracture through MRI 15 days back, since then iam on Ankle Brace, Rest and following Non Weight Bearing. I read most of the time navicular has poor blood flow and heaing time takes long and sometimes it will become non union, is it ? Should I undergo MRI or CT or X-Ray once again to understand the Current status whether it is in process of healing or not ? Currently I don't have any swelling or pain on midfoot since I'm in rest. It's been already 35 days since I had fracture and 15 days on complete rest. I'm getting scared about this fracture and wanted to go back to my work as soon as possible. Please help out team.
