Help? So confused!

Shanique
My first month using charts and everything else. and I though the temp drop before the positive opks was the ovulation dip. Was I wrong and is today's the dip?? 
Also the other pic. I took there two at the same time and one looks positive where the other one looks negative. 
And yes I know my temps are usually at different times so I know it's probably a but unreliable. 
​ 
​Can anyone help me out??
