positive ovulation test just 2 days after taking plan b??

K
First: is this a positive opk?? The control line is the one closest to the blue (left of photo).
I made the second photo darker on my phone---it's about an hour after I took the first photo. Same test strip.
Second: I'm confused because I took plan b on Tues (Dec. 6 at 2am) after my bf and I had an accident with the condom. I'm in my fertile week according to Glow, but not sure if I'd O'd before. tuesday was CD13. I usually have a 27 day cycle. Glow's predicted O day is CD14. 
Now it's Cd15 and if Plan B worked, I shouldn't have a positive opk test right? I'm a paranoid person and tta so I'm stressed and anxious right now. I am testing opk just in case--to see if my O day is delayed or nonexistent or if it passed and I'm in trouble.
Any insight or personal experience would be a tremendous help to my state of mind. thank you!
