What Causes Unusual Discharge?

Recently, my discharge has been abnormal for myself. I've tried googling everything and can not find any answers. The best way to describe it would be it is clear thick globs that consists of tiny round clear balls (that can be described to look like caviar).This was after my period and in the ending stage. Only sometimes do I experience an itching/ burning when using the bathroom. There is a lot of the discharge and I am worried since this has never happened before. Any answer would be appreciated!
