Change of dye run?

Aryana

Hello ladies. I have been ttc for a year now. I just got back from vacation two days ago and aunt flow was supposed to visit and never did. Lately she has been a day or two later than normal so i thought nothing of it. Today decided to take a test and this is what i see!!

I don’t want to get my hopes up in case it’s because of the blue dye but this seems pretty positive to me! Any input??
