Clearblue advance Solid Smile 1st use??


I bought the clearblue advance opk kit. I got a solid smile the 1st time so I wasn’t able to test again for 48 hours.

I had all the symptoms of ovulation and CM was clear/egg white.

We had sex two nights in a row, skipped a night, then sex the same day as solid smile.l, then again on predicted ovulation day.

I retested after the 48hrs and am now on my 2nd day of blinking smile.....?

I bought a 2nd kit to compare, and I’m getting a blinking smile with the new one too.

What’s going on? Has anyone had this happen??
