Charting temp

I don't understand my temp chart... I had a big dip but I know I didn't ovulate yet does the Temps look normal or at least how it should look prior to ovulation? I started my ovulation test on cycle day 7 2 days after my period ended since I'm very irregular but no peak yet... the 2nd line is light does that mean I'm close but just not there yet? Any help would be great... thanks ladies
