10 days of spotting!

Officially on my 10th day of spotting. Got last AF on dec 5th. From 12th Till 20th Jan had 3 BFN's. Haven't tested after that due to fear of BFN. Thought am having an off cycle not sure now what is happening! I am testing again on saturday before fixing my doc's appointment ( wishful thinking of being pregnant)  anyone had this happen to you or any similar exp or know what it means. Getting over stressed :(
