Ovulation question?!

Hey guys I am on cd 15 in my first round of clomid! Yay! Yesterday my ovulation test was super negative! I had no line on my cheapie and a blank circle on my clear blue! This morning I still had a blank circle. Took a test this evening and solid smiley and positive cheapie (I think)! I was told by my doctor to bd every other day. Well today is the other day! Should I bd tonight or wait for tomorrow night? Girls help! I will post a pic!

Also have you guys ever went from blank circle to solid smily without the blinky smily in between? How did it turn out?
