1st time OPK help!?

Sooo what do you guys think? CD 15 with 28 day cycles and 5-6 day periods. 1st pick is of the test by itself around 11am, the 2nd pick is the test next to the last few days of testing. Am I getting close? I took the test after I had drank a good deal of water so it might be diluted also! I don't have great eyesight so I just want to make sure I am not missing anything. We have been BD'ing for the past couple day and will continue to do so Just in case ;)
