Ovulation Day??

R
Does this 27% in this picture mean that was the day I ovulated? I have never used opks. AF was supposed to show on the 23rd according to two apps I have, it's the 25th and nothing. The only 'symptoms' I've been feeling are sore breasts, cramps and bloating.
​Since I stopped BC last March/April 2014 my cycles have been normal, never been late. Last month though I was about a week early. Not sure if that has something to do with it. Helpful input is welcomed! :)
