Ovulation help

Br
Ok so I started clear blue ovulation test yesterday and got low fertility but today I got a flashing smiley and is high fertility is that too soon ? Shouldn't it get to know my levels for at least two days ??? Also I had sex last night because my dh had been on a work trip and just got home we thought we had a few days before we got the smiley should I have sex every night I have a smiley or skip a day until I get the peek smiley ??? Any advice would be appreciated thanks
