Clearblue ovulation

Jessica

Hello my spouse has pcos, she was placed on Provera to induce her period, clomid for ovulation and also metformin. She started peeing on the ovulation sticks 2 days ago, all empty circles, BUT TONIGHT she pees and the smile isn't even flashing it is just a solid smiley face. So confused as to why it didn't even go to flashing, just straight to solid! Anyone experience this??
