What are my chances?

Janelle • Ttc baby #2
Trying to conceive a girl.. i think I have been ovulating on cday 15.. as of Tuesday (Dec 2nd) my clear blue advance gave me a blinky smiley in the evening, so we bd that night, blinky smiley wednesday evening , bd again, then blinky face tonight (thursday) bd again tonight... I'm wondering if tonight should be my cut off? Or maybe I should wait to see if I get my solid tomorrow? I know I am decreasing my odds of getting pregnant at all but I'm just trying this method out for now..
