Clear blue advanced ovulation test - do they work?

Jennifer

Hi!

So we have been trying 4 months. I've been getting super discouraged. My doctor suggested using and ovulation kit. I got the clear blue advanced. The first 3 days I got the empty circle. Then so far I'm on two days of the high fertility (blinking smiley face) but my CM so far is "not very fertile". Has anyone ever had a good experience with this with it not having matched up with cervical mucus. I'm super confused 😔
