Dollar Tree opk first time user - is this positive? (pic)

So, I am on cycle day 18 and I have gotten several BDING in and I always thought when I got sore boobs that meant ovulation occured. So, i stop bding. Just out of curiousty to make sure, my theory was correct I got a opk from the dollar tree and got this. I'm confused? My boobs have been sore for 2-3 days. Is this positive? If I bd today will I still have a chance or did I miss O?

I bded one day before period started cycle day 7, 9, 12, 14, and 16.

Thanks in advance!
