Stupid question??

So on April 18-21 I had my period. That week was the week of sugar pills obviously, so the week before that was when I technically stopped taking birth control. I was just wondering how long after does it take to ovulate. According to this app. it says I should start ovulating today. Just wanted opinions as my husband and I are officially trying for our first.
