Kindara fertility chart...

Hey guys, this is my chart shown on another fertility app (Kindara)... Is the horizontal line my 'cover line'? The vertical line is when I manually put in my O date... I'm not great at bbt charting because I have a naughty cat that likes to wake me up several times a night and I'm not a great sleeper in the first place so I'm lucky if I have more than 2-3 hrs sleep b4 taking temp.. But I do take it as soon as I wake up before anything else as instructed. I was a bit sick with a bad cold around 14-15 June so the high temp may have been from that. Would love anyone's input... Thanks :)​
