Question

I’ve been using the connect Clearblue opk on Saturday and Sunday I had a flashing smiling face. Then, on Monday and Tuesday I have a solid smiling face.

BUT when I used the Clearblue pink opk ( at the same time I was testing with the connect: to see for the LH surge) - I never had a smiley face at all.

Throughout the whole time I was using the connect I got four days of low, two days of flashing smiley face, and two days of solid smiley face. But the pink one never detected LH surge.

Question: what does that mean? Why did one of them come out solid smiley and the other was a big- O
