Should I be worried?

I've been having some symptoms so I decided to test, (stupid I know) 8 days before af due...I saw a faint line! 7 days before af due and a darker line and now 5 days before af due and much darker and also got a positive clear blue digital 1-2 weeks.

Should I be worried I got positives so early before my period is due? Normally I wouldn't test positive until about 3/4 before so this is a bit weird!
