How often should I ovulation test?

Diana • TTC #1 successful May 2016, thanks to Glow
I'm about to end my period in the next day. I've never tested before. Should I start around cycle day 9 for a 30 day cycle (which my last cycle was) like it suggests on the box or sooner? If there's no line at all can I skip testing the next day or could I miss a surge in that short time?
