Opk question

Tracey
So I have been using clear blue digital tests this round and I have been testing since monday. On monday open circle not fertile, tues same thing. Yesterday smiley peak fertility. Has anyone else just skipped high fertility time?? And still gotten pregnant if u did bd that night u got first smiley? Also does the test holder reset itself after peak fertility is detected? I bought a large pack that is suppose to be 2 months worth but holder is stuck on my smiley from yesterday.
