My first pic :) I'd appreciate your help!

Ok everyone! Please let me know what you think of this. 
I'm not knowledgeable about dye colors, etc. and I can't decide whether or not I see anything. I'm about four days late, and I have really long cycles (37-42 days). I just got on Metformin about a month ago because my doctor says I have PCOS symptoms even though my ultrasound shows no cysts. I did a digital test two days ago and got a "not pregnant" result. Anyone else on Metformin and have a really long cycle at first (but not pregnant)?
Anyone see anything?
