OPK help!

Need some help girls! This is my first cycle using OPKs. I've been tracking since CD 4 with easy @ home strips just to get the hang of it. To me it looks like my strongest LH day was CD 5 but I definitely didn't O based on temps.

I'm just curious if this all looks normal. I think I'm getting my strongest readings first thing in the am. The one time I tried middle of he day on CD 7 I got nothing...but I drink a lot of water so I'm guessing that's not my best time of day to test.

Thoughts???
