New to OPK testing - is this positive?

Justine
Hi!
I have been TTC for 3 cycles now and bought an OPK for this time around. I'm currently on CD 9 and have had 30 day cycles the last few months (unsure of length before that, I never paid attention). Glow says I won't O until 9/3, however I was really surprised by this OPK test strip as the test line looks so dark. 
To note, this picture was taken about 10 minutes after I tested. I know you aren't supposed to look after 5 minutes, but the test line came up right away. Definitely still lighter than the control though. 
Do you think this is positive?
