Short fertile window?

Last month doing the OPK I went from no lines to 2 lines in 1 day. Yes it was a 10 hour difference but that's huge. If you are only testing every morning or whenever, you are letting 24hrs past. 
Side note: the kit says I should be testing on CD 15. It could have been earlier. So yes I'm nuts but CD 9/10 it is in the future. Also, on CD 14. I saw it get a little darker and no change. I took 2 but threw it out. On CD 15 it was darker so I tested just in case. A few hours later too one and a digital to make sure the lines were the same shade. 
So this cycle I planned on testing at least 3 times a day to see how long it lasts. I use the strips and when I see 2 lines I use a didgital test to confirm. 
Take a look and pay attention to the smileys: 
About 12 hours (maybe) I no longer have a smiley. I think I haven't gotten pregnant bc it's too short and I didn't time sex right. Let's pray this did the trick. I did the BD CD 14 and CD 15. I wasn't planning on the smiley until the 17th so hopefully it works!
