Clear blue digital ovulation test kit

Jeni • We have two wonderful children and are trying for our last one. This is a very exciting time, I`m blessed!!
Has any one had similar testing experience during ovulation....
I started testing Monday and got the 0 everyday but yesterday which happened to be the peak fertile smiley face.. 
I never got the flashing smiley before the peak.. It must have skipped to it and then today I got another 0 not fertile sign. 
So one day day of being at my peak fertility ?  Does that seem right ? Can I still get pregnant?
