Am I close to get a positive?

Andrea • Got my first BFP at 14dpo (vvvfl 🔝) on cycle #2 for baby #1. Baby is due on October 6th 2017! ❤
Just took this clearblue opk and that's what I got. I'm thinking I'm getting close. Today is the 11th day of my cycle. I had a smiley face. Funny thing is that I had a circle (no face) 2 days ago and tested again today and it went straight to smiley. Is it normal to go from low to peak in just 2 days?
