Clearblue ovulation test (FLASHING SMILEY)

My dr and I have recently discussed that I may not be ovulating and she recommended me to start using these tests so I’m fairly new to this kind.

I decided to test at 7:00 tonight after feeling a bit crampy and got this FLASHING SMILEY. This mornings test was just the circle. I know I haven’t ovulated just yet but this is a good sign right?

A little background on this cycle, I bled for about 10 days. Stopped 5 days ago. tracking ovulation has been very difficult for me.

FLASHING SMILEY means I’m in my fertile window, correct?

Also what is the best urine to use for these tests?
