confusing stuff....

So I'm doing my first round of opk's this month and I'm a little confused to say the least... About 5/6 days ago I received what I thought was a positive? (First picture) and to be sure I kept on testing every day until now expecting them to get lighter... However they have not! They are staying exactly the same as the (second picture) what does this mean? Please any advice is welcomed I'm going out of my mind id like to think I have ovulated!!
