Clearblue opks - help!

[crazycatlady5]

Hi all! This is my first cycle using opks and I'm using the clear blue digital opks. Today I got a solid smiley face! Yay! But I have questions about it as I've never used opks before.

I have read about people getting flashing smiley faces on days leading up. I never got a flashing smiley, yesterday it was blank, today it was solid. Took it at the same time both days.

Also, if it's solid does that mean I'm ovulating today or tomorrow? It says it shows my two most fertile days.

And lastly, Dh has been away for a few days so we haven't bded since Monday! He gets back today so we'll have lots of opportunities over next few days. Are we safe or should we have bded yesterday too?
