When you get a test line that is as dark or darker than the control then you are having your lh surge and you will ovulate between 12-36 hours later. You're still in the lead up now you have some amount of lh but not a surge amount, so you might get a positive tomorrow and then ovulate at some point after that. If you are using the CB digi with only the solid smiley then you won't get it until your are having the surge, there is also the advanced kind that gives you a flashing smiley before the solid. Hope that helps!
