OPK help please :)

Second cycle following the pill, went straight from empty circle to static smiley on cb digi advanced. I tested using this because I thought I saw a faint line on the cheapy tests. 30 hours after getting my smiley there has been nothing on the cheapies - does this mean I have probably already ov'd? Or is the cb test so sensitive that it may still be a day or 2 til I Ov and before it shows up on the cheapy tests??

Confused

Hello
As i understand it, once you get your static smiley face ovulation will usually occur within 12 -48 hours, anything after that i think will show up as low fertility? so maybe 30 hours after, you had already ovulated??
hope this helps :)
