Clearblue Ovulation test

Hello ladies, So i had my Clearblue smiley positive ovulation result on Sunday (it was negative on Saturday but we had BD that morning). We BD'd sunday evening, I wanted to yesterday aswell but SO was tired... if we BD again tonight do you think we are still in for a chance 48 hours post-smiley? Has anyone got pregnant from BD'ing the day of the first smiley face?
